What is the best sealant/ epoxy to use to seal small holes in the back of an boat with an Aluminum hull??

Answer 1

jb weld works too.

Answer 2

It more depends on the size of the leek,it,s location and how much you are willing to spend, if it is leaking at a rivet, you can have the rivet replaced at a big truck repair shop, if it is a seam you can have it welded at a welding shop, if it is a small leak and you don't want to invest a whole lot of Money I would sand the area with a 180 grit sandpaper as good as possible and apply JB Weld and let it cure for 24 Hour,s before getting it wet, if the leak is in the transom area I would use a urethane sealant, JB Weld is very good stuff but it wont stand up to the pressure,s of the outboard.

Answer 3
