OK, I find that the laser paper is not bulletproof. I used two different types of copiers at Kinko's and both jammed up due to the paper sticking to the fuzing roller. I have used the Xerox copiers at Staples successfully twice at different stores. So far, so good. I tried overcoating the material with Lusterkote matte clear, but got too enthusiastic. It took the imager apart in a crazed pattern. I have a new set ready, but will let it "dry" for a day, then do several light coats over a period of a day or two.
I am using Lusterkote because I do not intend to clearcoat over the installed decal. It is going onto Coverlite covering with no paint applied, so must be fuelproof on its own.
More as it develops! News at 11 (one day soon).
