Hi everyone. I have a 2008 Silverado. About a month ago it got covered in tan house paint. I've tried claying with the smooth surface clay kit. It removed a lot of the over spray, but not all. I've also tried cleaner wax, and ultimate compound. Should I try a more aggressive clay? or is there some kind of chemical solution to remove this? Mostly whats left is very small dots of the over spray that the clay wouldn't pick up. Thanks for any ideas.
