Hello Peeps, I am getting ready to repair my front bumper from a minor accident. The bumper its the original bumper that came with the car and it has a couple of layers of paint form previous repairs. I am worried that painting over it again will cause the paint to crack and break with any minor bump. Is there a good way to remove the old layers of paint from the bumper. Is this even a good idea? Should I just have the Paint shop use bondo and paint over the old layers? Any advice.

Thanks in advance for your help,

Rolan
