Re: Burning Paint with PC 7424

You can burn paint with anything, but to do that much damage with a pc and a blue pad and 85, either you must have been doing something really wrong, like sitting ontop of it in 1 spot for a minute or so, or there was a problem from the factory.

If I had to take a guess, and it's just my guess, I'd say a problem from the factory - on one of my test bumpers something similar happened.

I did 1 pass with a cyclo, orange pad, and menzerna power gloss, next to no pressure, yet somehow I totally removed the clear, the paint, and went right down into the primer.





At first I thought this was how strong power gloss was, but this made no sense, so I went about 10'' over on the panel and, with maximum force, pressed the cyclo down and left it riding in 1 spot for a good 40 or 50seconds. removed it and no paint burn or any type of damage. So if I could apply 100x (okay, that's my estimation, lol) the force and heat 10'' away, it certainly wasn't the cyclo's fault, my fault, or anybody but the factory's fault.

Look at all the corvettes and cobra kit cars that melt when you machine polish them
