Truth Or Myth?

I was told about a ‘scratch hack’ many years ago that removes light scratches from car paintwork, within seconds and cost virtually nothing. Sounds to good to be true right? I’m talking about the trade (no so) secret of the commonly used product WD40. I often wondered if it was true but never had a reason to find out. If I had a problem with paint, I would correct and protect it properly.

A little about WD40 first.

I was first developed around the early 1950s by Rocket Chemicals based in California who later changed their name on the basis of their product. The name WD40 stands for Water Displacement 40(th formula). The actual formula is a trade secret and only been held in secure vault in San Diego California since 2018. The product has not been patented to this day, to do so the ingredients would have to be disclosed. So if you want to copy it you could, if you try and reverse engineered like many others have and call it a different name.

The actual product hasn’t been changed for many, many years. The product was initially developed for a company to protect the outer skins of a super delicate skin of a ballistic missile from rust and corrosion. It later went on to find a host of household uses such as lubrication, protection and cleaning when it became commercially available in the very late 1950s. I won’t go into that side of it, you only have to look at YouTube or TikTok for various household hacks, from removing sticky labels, worktops, hinges, freeing up bolts etc.

I just want to look at this product from a car detailing point of view. It can be sprayed under the car to freshen things up, stop squeaks, apply a coating prior to winter to stop door rubbers sticking, short term storage or just polish up a bit. There are other products out there can do these dedicated tasks better than WD40, but not all of them together like this versatile ‘Jack of all trades’ product can.

Now of course there will be pros and cons for this ‘hack’;

Pros

  • Cheap, cost of a cup of coffee
  • Quick to use
  • Instant results
  • Looks OK
  • Disguises light scratches
  • Forms a protection barrier
  • Can prevent rusting
  • Long shelf life

Cons

  • Temporary fix
  • Only light scratches disguised
  • Body shops hate it
  • Often used to make cars look better than they actually are
  • Can be messy
  • Oil based
  • It can mess detailing pads up

The fact is that if you are spraying WD40 on anything, you are spraying an oil based type of product. Like I said in the cons, it’s only a quick fix and the old scenario of the car lot salesman showing you a gleaming car gives this hack a bad name.

The opportunity I had to try this hack out was that I had to remove a couple or stuck on hard plastic sill protectors on a car. Once they were removed it had left a couple of light scratches on the paint, even with my gentle panel removal tools. They are difficult to see but they are there.

So the tip so simple; spray a little on the paint and wipe over. Nothing could be easier, you don’t even have to rub it in just spread it about a bit.

The result is a miraculous cover up so the exposed paint could be seen again without the scratches.

So, does it work then? Yes – sort of

On the deeper scratches it improves it, but it doesn’t wipe them out. On lighter scratches does.

How? It’s all down the way light is reflected from the paint. The oil settles into the scratch and makes the light ray dispersion more uniform thus it disguises the scratch or swirl. This is a similar principle to car paint glaze which is a more durable option which needs a wax to protect it. I explain this paint defect principle in much more detail here. or cut and past this to your browser: htts://onemanandhismustang.com/difference-between-waxing-polishing-and-your-paint-job/

The general rule of thumb is if you can feel the scratch with your finger nail, you have a problem. If you can’t feel the scratch then it can be buffed, glazed or hidden in one way or another.

As the WD40 is oil it will eventually disappear due to the elements if on an exposed area. If the product is rained on a lot, it will need regular applications. So, if you want to mask or ‘hide’ a light paint surface imperfection, then you could use this product on a temporary basis. If you are going to buy a car, gently feel the paint to see if there is a oily film to the surface.

Another down side is that dust can settle in the WD40 spray and stick to it, so wiping it away could introduce more problems. The reason body shops don’t like it is the fact it’s oil based and once on your hands can be transferred all over the workshop. To clean it up properly in order to spray paint anything properly, this makes it all the more time consuming.

I tend to carry a small ‘sample’ sized can for a couple of reasons;

If you get a stone chip and can’t get to fix it for a while, spray the area with the WD40 and it will form a temporary barrier until you can fully remove it later to fix the chip.

If you are suffering from damp in your distributor cap (back to old school cars now) or HT leads etc, you can spray this to disperse the water. After all that was it’s sole purpose for development.

Did you know?

To get those super smoky burnouts in Hollywood films easily, they used an application of WD40 on the tyres! Not that you should ever do that of course, as it could be frowned upon by the local law enforcement agencies. 😉

Hands On Or Off?

Last weekend I had the chance to use my new bit of detailing equipment. The particular item isn’t my first venture into this area of car detailing. I’m talking non-touch drying or air blow drying.

There are various methods to dry a car after a good wash and shampoo pampering;

Chamois leather, old school method.

Pros:

  • Great for large surfaces
  • Very efficient at absorbing water
  • Only one is required to dry your entire vehicle.

Cons:

  • Requires water to use, not ideal for waterless eco-friendly sprays
  • Potential to scratch vehicle if used incorrectly
  • Dries hard, not as convenient to store

Synthetic Chamois Leather, modern take on old school

Pros:

  • Great for large surfaces and small areas
  • Very efficient at absorbing water
  • Softer than traditional chamois
  • Easier to store

Cons:

  • Needs water to work, not for waterless washing
  • Potential to scratch vehicle if used incorrectly
  • Needs regular rinsing and wringing to use

Micro Fibre Towel, modern technology

Pros:

  • Great for large surfaces and small areas
  • Super efficient at absorbing water
  • Comes in many various sizes
  • Varying levels of plushness
  • No need for water, ideal for waterless cleaning
  • Can be used inside and out

Cons:

  • Cheap cloths can leave small fibres
  • Can leave streaks
  • Easy to store

Air Drying, dedicated air stream (hence non touch)

Pros:

  • Great for large surfaces, gaps and small areas
  • Very efficient at drying
  • No water spots
  • Non Touch drying

Cons:

  • Needs electric power to work
  • Can blow lose debris on the car if used incorrectly
  • Bulky to store
  • Expensive
  • Can be noisy

My new equipment is the Carbon Collective Air Force 1 Car Dryer Limited Edition (but only the colour) where I just completed a full in depth review. Carbon Collective are better known for their quality coatings and treatment products more than their accessories. This car drying unit of theirs is a cylinder design which is very similar principle to a follow along vacuum cleaner, but it blows air instead of sucking up dirt. The point of this unit is blow a filtered jet of air over the area to be dried. Not just a car, but anything that needs drying like; motorbike, cycle, household use, boat etc.

The forced air stream will dry the area without the need to touch the paint so it won’t cause any marks or swirls on the paint from the drying process itself, unlike a chamois or microfibre drying towel which could introduce swirls or marring. Not wanting to repeating myself too much (from the review here), there is a 5m mains cable, a generous reinforced 5m hose, adjustable air flow dial and an optional fan heated function. The base unit has lockable casters in each corner to stop or allow movement as required.

The nozzles are silicon tipped so any accidental contact with the surface being dried will not mark it. Each of the fittings has a bayonet style locking feature with a sealing ring to stop any unwanted air direction. With a maximum of seven cubic meters per minute being forced out through a small nozzle opening it needs to be securely held in place.

Perhaps the most important thing about this product is the filtration. Not one filter, but two, even though the accompanying book of words states one filter. If air is being sucked into the unit that low to the ground, then accelerated out with 900g of force, then any debris moved at that speed has the potential to be literally fired at the paint work. Think of hail stones, but on a much smaller scale. The removable filters are washable or cleaned with an air line.

Am I converted to this ‘non touch’ method? Well yes. Apart from the cost of running a 2800w motor and potentially a 600w heating element on top of that at the same time. The cost of running this for one hour (as this is published) will be approximately one British Pound per hour. Saying that when being caught out at a car show when it rains then the microfibre towel is still used of course.

I have lost count of the number of times I have gone to wax a car and found a water drip or a water spot left on the paint surface, it’s rather annoying at the best of times. This process does away with that as the air gets into the gaps and hidden areas where the water can sit. The down side is getting the equipment out, setting it up and putting it away again. Compared to taking a drying towel out the storage draws wipe over the car and put the towel in the washing basket when finished, there is more to it. But, the air drying is more thorough, providing you make it more thorough.

You will need to be careful with the air stream at the lower parts of the car not to blow loose debris around and potentially back on the car. Turning down the air force can be a real help under the wheel arches or on wheels etc. Once you master the technique is great. Probably not for the average weekend washer of the daily family car. But for a detailer this is a great addition to the detailing inventory. Not the cheapest of items, but I will get good use out of it.

I tried to film the process with hand on the phone and the other drying in the left hand video. The right hand video is just to show the force of the air from the wide opening nozzle blowing water around on the floor.

I do have another blower which is hand held MetroVac Air Force Blaster Sidekick SK1.

This is a 950w single hand held unit which has advantages and some disadvantages over the Air Force 1. I will get round to reviewing this bit of equipment very soon.

Nearly back to starting car shows again, and looking forward to that and getting some fresh air, well as much fresh air as you could get around classic car fumes! 😉

More Reviews Coming

A few months ago I was approached by Jim Jeffrey from a car detailing website called World Of Shine. We got to talking about a topic that was a confusing international problem. We had some good chats and he liked my chart that I had put together in December 2019 and posted on my pages here. This was my big article explaining the actions of various dual action pads and why you need them. The DA colour comparison chart comprises of the big name manufacturers on the DA pad market. Jim asked if he could share my chart with his subscribers to which I agreed. He wrote that article called “pick A Color – Any Color” which was posted here august 7th 2022, where he referenced my chart.

To download my original PDF format of the DA Comparison Chart, click here.

Thanks to my friend over the Pond Jim for giving me a shout out.

Now that the car show season (in the UK) has now all but finished, the next few posts will be focusing on little upgrades, tweaks and a few more reviews. With that in mind, a good friend of mine Craig had just bought a new car for himself, a MK 7 Golf GTI (2.0ltr turbo in fact). He brought the car over for me to have a look at and an excuse for take it for a drive. Once he was here it was a good reason for me to have a little drive (OK thrash) around the relatively deserted roads of my village.

The car looked a bit grubby when we had finished, so we had an impromptu detail session. We got out the snow foam, Absolute Rinseless Wash, spray wax and final quick detailer.

I will be reviewing the new products we used very soon which comprised of a rather expensive sponge, spray bottle and P&S Absolute Rinseless Wash which has been making some good noises around the detailing circuits.

The finished result was pretty good for a day’s work. To do it properly we should have clayed the car first, clean slate removal of old products and layered up the waxes and protection. We didn’t have time for the full process, so we just made sure it looked clean on the way home.

No sooner had he parked up at home, it started to light rain on our hard work, but the beading was good to look at.

The only down side? Craig ate most of the donuts! 😂

Americana (last) Car Show of 2021.

This show was held at Stonham Barns organised by the Knuckle Busters Car Club on the 19/9/2021. This particular car show was for American cars only and is usually well supported and this time around that was no exception. I arrived early and I was asked if I wanted to attend in the centre ring. Why not? Early bird gets the worm and all that. I parked up next to some stunning cars which made my car look like a Matchbox or Dinky toy!

I parked next to a massive Buick that could only be described as a ‘land barge’, such a nice car it was too. Me and the owner sat in our chairs and chatted most of the afternoon.

I decided to have a wonder round and take the pictures before the public came in.

I thought I would batch the Mustangs together here, but there wasn’t as many as I thought there would have been.

A car I had seen a couple of shows earlier, but I couldn’t get that close to before. Another iconic car from Ford – the Torino. I wanted that car so bad as a little boy. My nan even knitted me a Starsky jumper. Thinking about it; I still want one!

This Corvette was beautiful.

The ones next to it weren’t to shabby either.

Back to the other cars now and in no particular order.

Truck Time. I was speaking to the guy who owned the Viper powered truck, he said it scared him on two levels; one the petrol it used and the other was that the truck wanted to kill him!

We have to pause and and look at what Pontiac did when they created this gorgeous and much coveted car.

And my no means least, I was also strangely drawn to the taxi as well.

Throughout the day there was music and a really good live band with plenty of 50’s rock & roll with a little dancing as well.

The day was dry and warmish and didn’t rain for a change. A great day and so much American iron I wanted to drive home. But, I could only drive one home and that was my little lady.
