apply a satin or semi gloss paint with a brush or q tip(roll it) that will leave a textured finish , i do not recomend tape b/c temp change could shrink the tape
I was figuring the tape might shirink or peel.. what do you do for the 'seams' of the vinyl top? I was on that yellow Dart you did, you have the seams on the roof.. what did you use to make those?
