fixing leaky bottom?

i have a 12' aluminum boat i am completly fixing up to sell. it is rivited and has a leaky bottom. not bad but a good amount gets in. i have heard about steel flex is that stuff good? does anyone no about it? also i found something called dura fix. its pretty much aluminum brazing. cananyone tell me about that? thanks everyone!

That all depends on where it's leaking. Is it a rivet or a crack? if it's a rivet, try rebucking it. Easier to do with two people. If it's a crack, you could braze it or better yet, weld it.

There is a TON of info on this board about using sealers like Gluv-it, SteelFlex, 3M 5200 etc. They all work well in certain situations. However, there is nothing better than actually FIXING the metal ..... weld it!!

Look around your area for a fabrication shop, off-road shop, hot-rod shop, even basic body shops .... anyplace that welds on a regular basis. Call them up and explain you need a few short aluminum welds. Most likely you can get all your leaks welded for less than $100 .... which is about how much you would pay for some good sealant anyway.

Oh, if its just leaky rivits .... rebuck them and be on your way.

3m 5200!! Love the stuff!!
