Just received my Grabber C stripe kit from Graphics Express. Other than the basic instructions does anyone have any advise or tips on problems I may run into ? I'm a little concerned because the tech said that the reflective material is thicker than std. graphic material and moisture could remain behind them and form a blister and pop later. Also concerned about when to wrap the remaining 1/4" ends around the doors and fenders (don't want to do it too early or too late) Any advise would be greatly appreciated.
