03. Can the DeVilbiss Bumper Prep Pad be used on primed bumpers?
The current bumper pad is aggressive enough to adequately abrade most primed bumpers. However, it is not rigid enough to level the primer layer (remove the uneven spots) on the bumper.
One can use the current bumper pad to clean and degrease a primed bumper. But it will not level the primed surface sufficiently and a sanding process will still be required.
