Flex Seal Paint on Inflatable?


Sep 14, 2021
I have a FoldCat inflatable pontoon fishing boat, bought it used but it still works great. I had put a layer of Flrx Seal paint on the bottom of the tube seams for extra protection from scrapes, but also as an extra measure to protect the seam/seal. I was wondering if I were to paint a layer of grey Flex Seal paint on the boat if it would have any negative effect, or if it isn’t suggested… this would be as an extra layer of protection, I have no holes or leaks. Just want this boat to last as long as possible. Any advice would be appreciated. Also, if anyone has any modification ideas I’d love to hear them.

Welcome to IBoats,

Will need more than just one coat of said product ir order to achieve a thicker protection layer. Better will be to glue two large PVC strip patches under the tube's portion that contacts any surface on the whole tube's length.

Inflatables must not be beached at speed when going out of water or dragged continuously over hard surface or risk damaging the PVC fabric which it's much thinner than heavy duty similar inflatables. If plan going that route, check Defeder, West Marine for a PVC roll and 2 part PVC glue...

Happy Boating
