RE: Sig Hog Bipe
Alex, I used a similar type of striping that wasn't heated on, only self adhesive backing. I used clear dope and a small brush to run along each stripe to seal them. So far, it seams to be holding up well. I have heard that clear nail polish will serve the same purpose.
Referring to the earlier discussion of bonding the covering to the ribs, that is the technique that I used on all my previous covering jobs. However, on my Hog Bipe, I only sealed the edges with the iron then shrunk the covering with a heat gun without pressing the covering onto the entire wing. I am now sold on this method. There is a major difference in the look that it provided. The wings are much smoother and "glassier", very satisfied.
