Question about shaving rear side markers. My rear bumper was recently damaged and a friend of mine is already repainting my front bumper, hood & spoiler. When I asked about shaving the side rear markers we were unsure on how its accomplished.
Its a large area to be filled, and one technique we though of using was cutting out a piece of material from another damaged bumper and apply that to the open area where the lights were and then using body filler to fill in the area.
Are there any other methods, hints or tips you can give me before we dive into this project?

"bondo" does not stick to plastic bottom line, period!!!
if your bumper is yellow in color, then it is polyurathene, the methos you talked about is correct, here is what i would do
lightly grind the plastic on the bumper both side and the piece your going to mate to the bumper
i would plastic weld , the piece on, and then apply a coat of repair material to both sides of the bumper, and panle bond sticks to plastic too, its true, 3m and fursor both there panel bond sticks
this takes experience in plastic repairing/modifing, so iam guessing that its the bumper you are talking about right
if it is not yellow in color, before you apply any type of repair material to this type of plastic you need a adheshion promoter for anything to stick to TEO,PP, TPO, those are offlien plastics and need a promoter
hope that helps

GEt 3M part # 8237. It's a 2 part that will work wonders for what you're trying to do. Just make sure anything you try to stick together is roughted up with 36 or 80 grit and wiped clean with Prep-sol or alcohol, and have at it!

when plastic is repaired correctly, it will last the lenght of time, i fix allot of plastic i love working with it all types too, not just polyurathene, the correct way to prep plastic before anything is applied is to use glass cleaner, yes glass cleaner, the best thing for plastic before the repair process starts, 3m or fusor is the best product out there in my opinion
