I had the 'pleasure' of knocking out some horrible paint damage on a car this week. This is the worst acid rain damage I've ever seen. It stopped my thumbnail in several areas like a heavy scratch. Even the glass was heavily etched. It was an '09 HHR w/ 14k miles. Excuse all the cell phone pics but I think it still shows a very obvious progression.





I both attacked it with my Makita rotary buffer and yellow synthetic wool pads. 3M's rubbing compound was put to the test on this one. Its very aggressive at 1600-1700 rpm and moderate pressure. The pics speak for themselves.



After a machine polish and swirl remober:





It took better than 3 hours to get it that good on 98.5% of the car. There were just some spots that were too stubborn to come completely clean without wetsanding - My job was to save it from the paint booth so mission complete! 3M FTW!!!

Comments welcome

 

Wow I have never seen acid rain like that.

 

thats crazy man

 

damnnnnnn. nice progress.

 

More pics....it looks like you did a good job

 

What do you recommend for acid rain on windows? I've been told that vinegar works but it did nothing at all.

 

Use 000 Steel Wool and a liquid glass cleaner or mild soapy water. If all else fails, tape up your window edge mouldings and buff them off.
