Hopefully the pic below is clear enough, but my footpad glue has given away from the plastic base plate. I recently tried using Selleys Ultra Repair and not only was it expensive but it lasted two kite sessions.

I am considering using my hot melt glue gun or maybe some Sikaflex silicon adhesive but before going down that pathway would like to know what others have had success with. Obviously it has to have water resistant qualities and a level of flexibility.

Cheers for the advice!
