Burning Paint with PC 7424

[sullysdetailing]

I never seen damage like that from a random orbital buffer, the surrounding paint wrinkled like it was not even cured. Need a professional to chime in here ...

That what I was thinking.
It is nearly impossible to burn the paint with a DA.

It looks like the bumper was repainted and it didn't cure right. So the heat that the DA produced caused the paint to lift.

I saw this same exact type of burn happen, only with a rotary. It is (like Dana has said) a burn. And that too was on a plastic bumper - factory paint, about 5 years old.

I burn my paint slightly while working on my car outside in the strong heat, direct sunlight with a 7424 :/ lol. It's barely visible, i didn't burn it much, just slightly. I have no idea why i did it under the sun.

Historic thread I know... But you do know that bumper covers and trim pieces on most modern cars are no longer painted but "coated" with a film that is a dead match for the paint color. Kind of like contact paper. The only way I know this is my older brother works for a supplier to the big 3 who makes bumper covers and trim pieces. Before these pieces leave, they're "coated" instead of painted. The OP's picture looks as if the coating has torn or ripped off.

Bumping old thread, what about us that don't have an inside option to use their DA? Just use out of direct sunlight and practice normal DA technique?

Do it in the morning before the paint gets too hot. Also don't do it on a windy day, because that can throw dirt onto the car to get between the buffer and the paint and cause scratches.


The reason people buff inside is because the car stays cooler even when it's a hot day, and it blocks wind to prevent dust from getting on the car.
