I have used alot of automotive pinstriping but gave it up when it wouldn't stick for long. I now use Monokote Trim sheets and cut striping or stars or whatever. I doesn't need a clear coat and adheres very well. It is considerably heavier than Monokote or other film covering so I only use it for trim. You can use the automotive striping and spray it with Lustrekote Crystal Clear. Evrything I build has an American Flag on it. Most of the flags come as small stickers and are not fuel proof. I use the Lustrekote to cover and have never had a problem.
