Default Aluminum boat repair?

I've a 14' Lund with alot of weaping and leaking rivets.I used marine epoxy to fix a bunch from the outside which worked on some but not all.Does anyone know of any other kind of material I can coat the whole boat with that will make it water tight?Linex won't work,slip plate neither.Has anyone used M3-5200(marine sealant).I don't know if this will last.I have to get back to F&T Boats in Edm. tommorrow to find out if they can get anymore of the stuff they use,he didn't tell me what it was they used though.Any info would be great as I've about run out of ideas. Thanks guys.

Default leaking rivets

I had the same problem years ago on my old Lund before I got rid of it.

Sealers and/or epoxy on the rivets is only a tempoorary solution at best.
Since the hull flexes and vibrates etc. when you use the boat most of the leaks will unseal themselves.

There is a repair technique that you can try - retightening the rivets, but you need to be very careful. Partly fill the boat with water or float it so that you can identify exactly which rivets are leaking. Identify the leaky rivets both inside and outside on the boat with a marker.

Using a steel hammer and a bucking tool or chunk of steel shaped to fit the head of the rivet (its rounded). You will need a buddy to help you. Strike the flattened end of the rivet inside the hull with steel hammer. Be carefull with hammer or you will put a hole in your hull. This method takes a lot of patience and a good friend.

Barring that the only other way to stop the leakage is to find a good welder and get him to spot weld around each rivet as needed. I finally had to go this method when the leakage got too bad. The reasonsmy boat ended up leaking so much was too many miles on gravel roads that actually thinned the aluminum bottom and caused it to flex too much plus a LOT of pounding in rough water conditions - finally just wore the boat out.

Who got to go underwater to help with this procedure?

It must have been you since you are the one asking the silly question.

I am just trying to help someone out. Obviously you need to read between the lines a bit.

Well, What kind of repair do you want. It is a structural issues and in that tig welding is referred method and there are aluminum epoxies out there that would work for a repair.

Why not drill the leaky rivets out and put new ones in? Buy rivets and rent the rivet gun.

If buying new rivets, get stainless steal ones and not aluminum. A little more expensive but alot stronger. Check at your local marine dealer or repair shop. That bullfrog repair kit sounds good as it comes with epoxie for the sealant.
I think princess auto has rivets.
