Question

I meant is the mighty putty waterproof enough to plug a hole in the hull of a boat.?

Answer 1

Good temporary repair.  Epoxy hardens and does not flex well over time.  Depending on usage, it will not keep a tight seal forever.

Answer 2

The absolute best product for patching holes is Splash Zone.  Cures underwater, sticks to anything.  It will not fill a large hole but it will make whatever material you have to cover the hole stay put.

Answer 3

If you have a small leak I think it will probably hold you untill your next haul out.  I'd still keep an eye on it.  I have a small leak where my swim platform is bolted on. I have it there.

Answer 4

no  its not use fiberglass to repair it

Answer 5

I would go to a marine store and ask if this mighty putty is as strong as something called "Bondo". Also if the is a big hole you might want to consider getting a hull patch.

Answer 6

The waterproof putty patching makes it possible for a lightly damaged boat to return to port for proper repair. Yes, it will plug small holes in the hull. For holes more than 1", use a dowel.
