The 3M Vinyl tape worked nicely. I had it on for nearly a month. Pulled right off without tearing or shredding.
Only problem was the glue is pretty strong. My hull is painted with one-part Brightsides, and a few bits of that lifted off when removing the tape. No problem with the two-part paint on deck. Would be fine on gelcoat.
Nothing to see in this picture. I just thought is was funny the guy had his license plate on upside down
