Tape really is not needed unless it has worn right through.
The resin is enough and needs to be as hard as possible for longer wear.
Tape each side of repair so no clean up is needed and lie hull in sun. Heat will help the resin to go off quickly so it can be worked.
Glue pwder makes a thicker and very hard compound but must be respected.
Cut any excess off with knife when half set and repeat next day until desired thickness is formed. Sand clean with lessening grades of wet and dry.
