Wetsuit Repair Iron-On Seam Sealing Tape 1 Inch x 65.6 Ft Seam Sealing Patch Waterproof for Neoprene Wetsuit. Worked pretty well for an iron on tape. Make sure you clean it well with alcohol and use a sheet of paper between iron and wetsuit. Take your time heating the tape until you see glue lines all around the tape. It held in some spots and started to come off in others after a couple of sessions. I have tried to re-apply it with the iron, but found that simply gluing it down with Aquaseal or Aleene’s Fabric Glue worked well. Only use glue if your iron on efforts fail. If you have neoprene missing, then the Aquaseal Neo will work better to mend the gap. You can put the tape over it after you mend it.
