pontoon sealer

[rooster4321]

Is there a product I can put in the back drain plugs of my pontoons that will coat the bottom of the tubes from the inside to seal them?

What problem are you trying to solve?

I coated the outside of mine with por-15 and it really worked well.

I have a pin hole in the bottom of one toon and I can seal it from the outside , but if I could put something on the inside it might last longer.

JB Weld to repair the pin hole from the outside and not have to worry about inside.

Or better yet, have a welder fix the hole properly.

When the boat is in the water, the water is trying to push in through the hole. The air is not trying to push out. So a patch from the outside would work better provided moving water didn't pull it off. .... I agree with the welding suggestion. I suspect the hardest part of the job will be getting the boat and welder at the same place and time.

jb weld as a temp fix...they make a product that can be used underwater. Then get it to a welder for proper repairs....especially if you leave the boat docked
