Anti-Chafe Tape is used to protect sensitive areas of your boat or equipment from abrasion. Anti-chafe tape is designed to be used under shrink wrap to prevent any type of chafing where the shrink wrap may rub, as on the hull of the boat, on painted surfaces or on Plexiglas. It has a very light tack adhesive so it will not leave adhesive residue, and is used only as a buffer.
