Repainting car bumper due to chips - how much sanding?
I sanded the worst spots where the chips were the largest.
Do I need to sand the entire bumper down to bare metal? Or enough to get adhesion with primer, even if there are still chips that can be felt, and those would be filled in by the primer?
Just wondering how much more sanding I need to do...
Not looking to do a showroom job, just good enough to not be noticeable after repainting is done.
