Thanks Cory. I did not mask the fins or letters, no need to call Hovander for an eye exam. I just lightly wiped the fins and letters with WD-40 to prevent the paint from sticking well and sprayed directly in the 110F heat, paint started to krinkle very quickly. There were some small scratches that I wanted to clean up anyway so removed the fin/letter paint starting with 180 grit sandpaper followed by 400 grit. IMO the WD-40 definitely helped the paint come off easier.
