hHow clean is clean? I have scraped it with a a scraper, wire brushed the residue left sticking to the joint. There is still a thin layer of sticky black residue left from the wire brushing on parts....
Well I stuck down after every thing dried. its about 80 degree or so here where I live so the heat helps the tape flow also. Here are the pictures of the final project. how many of you can stand on you roof in sandals right now. lol
