Got it!
I'm having second thoughts on painting the Dinan badge gloss black. In order to do it, you'd have to unpeel the front tape, which would destroy the ability to place the badge on straight with the correct spacing. The badge is not connected in any area...it is literally five letters loose.
But a silver Dinan badge with my my gloss black M3 badge would look tacky. Maybe I should just go back to the stock M3 badge?
Or maybe I should just press my luck, get it painted, and place each letter up one by one carefully. I could just get some painters tape and tape the bottom of the trunk to act as a guide (each letter would sit above the tape line). I'm worried about getting the spacing correct between each letter.
