*$%@# SCREWED! Went to do this, but dealer put a screw through my bumper! Why would they do that?!

< (My emotions when I see my dealer for next service)
Thinkin of using some of this to fill the hole:
FORMULA 27 ALL PURPOSE FILLER - American Marine Supply.com - Quality nautical equipment and accessories for the recreational and commercial boating community.
and then paint over it with Honda touch-up paint to more closely match the color.
Good idea, or no?
