Questions on paint thickness readings

[Bdubbs]

Hello everyone.

First off this is my first time using a paint thickness gauge. I did calibrate it. But wondering if I'm still using it right.

I did test different areas on all 3 cars. But the readings I'm showing you are on from the roof of the cars.

First is a factory paint on a 03 cobra mustang which seems pretty normal.

Second is a 90 mustang that has been repainted at some point and I did a paint correction on it almost two years ago. But it has rarely been driven since. Can this even be right? I tried it several times and got anywhere from 25-32ish.

The 3rd is a 67 fastback mustang that was also repainted at some point. I can't tell if it's a single stage paint.

Any help would be great [emoji106]https://uploads.tapatalk-cdn.com/20220119/c433b0c9dea10db44b148022ace8351f.jpghttps://uploads.tapatalk-cdn.com/20220119/a34666f159360ed7f85b97189871d519.jpghttps://uploads.tapatalk-cdn.com/20220119/2b30a2daba0300339d515ed54a327e0a.jpg

I’d say the first thing to do is take multiple measurements on the same spot and see what the consistency is between readings. This will give you some confidence of the meter results. Alternatively, using one spot with multiple readings may help you dial in the method to use it to get consistent results. Step 1 with a meter is getting consistent results, then you can start to use the results to make decisions.

As far as the factory paint, that seems reasonable. The 3rd car with a repaint also seems reasonable. The 2nd car with 30+ is way overkill and may have had an inexperienced painter than put the paint/clear coat on way too thick.

You may want to take a measurement under the hood to see what you get as that is usually just paint without clearcoat, at least from the factory.

This thread is another data point to support my position that PTG's are not typically necessary in the detailing world.

What useful information have you gathered from such widely varying measurements? The only information I can gather is that two of the vehicles have been repaired/repainted, but a good visual inspection would likely provide that same information.

How do any of the measurements you made help with any decisions on polishing? They don't in my eyes.

I just bought some Griot's Boss fast acting cream and perfecting cream polish that I plan on trying out.

03 Cobra seems right

The '90 Mustang likley has some light filler in it or it has been scuffed and repainted about 8 times lol. Take more measurements from the rest of the vehicle.

The '67 seems fine for a car scuffed and repainted 2 times.

You wanna see if it's ss paint take a polish and a microfiber and rub it on there. Red transfer= ss

Just take a white cloth and a little compound or polish. Hand polish a small spot to see if you get any pigment transfer. If you do, then it is not clear coated. If you get no transfer, then it is clear coated.
