Get the masking kits from Ames; they also sell the correct paint, which turned out to be DupliColor. I painted my Rallye II's over 15 years ago using their masking kits and people still comment on how great they look. Hope this helps.
Do you know the duplicolor codes for the colors? and about how many cans will work?
