Looking for a quick repair for your dinged board or boats? I’ve been using Foil Tape for years.  It sticks on most wet surfaces, provides a stiffer surface than packing tape, and can be carried flat in a slim waterproof container while on the water.

When you need to fix the ding with epoxy, it pulls off your board easily as well.  I also find it stays on better than tape which can peel of while in the water.

Recently I was able to use it to attach a damaged fin onto a board and surf a session without any issues.

Find it at most hardware stores such as Home Depot.
