I removed the interior ones and am in the process of removing the ones at the mast. The ones at the mast are proving to be a pain, pad came off but adhesive has held tight in small areas about size of dollar, against everything I have tried so far. Heat gun, acetone, Mr Clean pads, and scraper has gotten them down to quarter size. Trying goof off then Oven Cleaner next. Everything seems to get the edge but not the center of the blob. Really not much left but it looks bad. on the bright side it SAILS JUST FINE! I plan to leave mine gone since they cost so much and almost all functions are from cockpit.
