Just Finished Mine Last Week
It was easy. I used a window paint scraper that uses a single-edged razor blade. It came right off with no blow dryer or heat gun. I used mineral spirits to remove any residual adhesive. As Sherry says, the shadow remained. I used rubbing compound and electric buffer. Then 3M-cleaner/wax. Then, the shiney spot looked so good, I rubbed, buffed and waxed the rest of the hull. The shadow was still very faintly visible. On the new name, I "upsized" and it almost completely covered any remaining shadow. The graphic company that made my new lettering said the shadow would fade more when exposed to the sun. BrianW
