Hi all, Can you provide me some tips how to successfully paint correction (light swirls) on bumpers that are plastic w/ scratch resistance clear coat (i have a BMW)? Can I use the same pads and compounds to remove defects on the plastic bumper vs. metal door panel? Or should I never use a cutting pad on anything plastic because it will melt through the paint? Also I've been getting mix advice on moving the buffer. Some tell me to move it quicker than you would working on a door panel, some tell me to use same pace as you would working on a door panel. All of these tips are confusing and I dont want to burn through anymore paint. Im using a dewalt849 with soft buff pads from megs. Currently i have SIP, 106ff, and Megs #82. Please advise.
