I finished the trim paint without a problem. There were a few spray leaks under the masking hold down tape but I was able to clean that with "Q" tips and denatured alcohol. I used to use masking paper on a roll but the last roll had some spots with holes. That's how I found the denatured alcohol trick. I searched my brain and came up with a new masking material. Newspaper bags. My paper comes in a plastic bag every day. I save them and cut them open for use. The bags have printing on one side, I keep the printing side out. Then I got some truck side steps that were packaged in large plastic bags and they work just as well but are a bit thicker. Iron on covering has the backing sheet that works well also.
