OK, a couple of questions- I have my old pac man control panel, stripped down to the metal (and wood).
1. Should it be painted, primed, or anything else before putting the adhesive on?
2. The two middle carriage bolt holes (larger than 1/8th of an inch square, less than 1/4th) are now redundant with additional controls I am putting in, and fall right in the middle of the characters on my artwork. Rather not put the bolts in, buy my fear is that I will feel the holes under the vinyl, or worst case scenario, the vinyl sags into the hole. Any thoughts on how to fill in the hole on a thin metal CP?
