I have tried it once on a Valkarie flame job, did ok with 1/8" pinstripe tape but when I sprayed the clear some of it started to lift...Also you could see the flame edge in the outline since I did lay it on the base....a no no....I was thinking about clearing then sanding, outlining, then clearing again but I am leaning toward getting a brush and painting the outline.....or if I suck having the outline painted on....
