GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
Go to a automotive store and ask for a 3M stripe eraser. No sweat and no need for the belt sander.<br /><br />You could also try a hair dryer and a plastic scraper.
If the hair dryer doesn't work, Harbor Freight tools has a heat gun for $15 that kicks out some serious heat. Use that with a windsheild ice scraper from Wally World.
