As a younger nipper in the bodyshop business I learned that if using masking tape and you sprayed them with lacquer the paint has to be completely dry before pulling the masking tape. The edge will feel rough. If you mask tape the stripes and use acrylic enamel, REMOVE THE TAPE WHILE THE PAINT IS STILL WET. The stripes will have no edges, no rubbing needed and if you have taken time to mask the stripes with slightly rounded ends the effect looks virtually the same as a rolled-on stripe. An airbrush is not necessary, a Devilbiss or Binks cup gun works great, just don't load the job up with too much paint. A good fingertip gun works well also. We repaired new Fords a lot, the '77 thru '79 T-Birds were striped everywhere including the roofs. lol I never got one back for the striping using the wet tape-pulling method. We could copy vinyl graphics into an adjacent repaired panel with paint doing the masking and removal of the tape when wet.
