painting bumpers?

[imported_Darkwave109]

I kno how to spray metal objects and wat paint ect ect but when you colour code your bumpers wats the process
just normally you would use a form of sandpaper on the surface for the paint to stick.....but bumpers are plastic ect ect

You can get a primer for use on plastics obv you still need to sand it down etc etc ..
