It might be Fuzzies, although I always use a lighter to burn off any fuzzies visible. Also it happens on the blank itself where I've coated (at the same time) the signature area. This might be occuring as well because fuzzies are being transferred by the brush when appling the finish.........Maybe?.........Any other thoughts? I am lining up a list of things to check to rid myself of this problem . Like I said it's new for me, and aggrevating. Nothing worse than doing an excellent wrap job (not to mention all the rest of the work involved) than having to do double time to straighten out a finish problem............... First thing I'm going to do is check my thread spools , maybe they are getting old or maybe I have to go to a different brand.
