Sealing up a boat question

I've got this old Aluminum boat and I'm trying to fix the small leaks and cracks but their several. Is there a product that any of you know of that I can just brush or roll on the bottom of the boat to seal it up? I thought about having it Rhino Lined but that's a little more money than I want to spend. They told me it would around 250 or so and the boats old enough, it wouldn't be worth it I think.

Any ideas or suggestions would be appreciated.

That Rhino lining is sounding better and better as the day goes on! lol

Anyway, any other idea's for a brush or roll on type product would be greatly appreciated!

Put an automatic switch on the bilge pump and you won't have to worry about flipping it on every hour. I don't know if I would put a spray on bed liner like Rhino liner on the outside of the boat. It will also add weight to the boat that you may not won't.

Try putting the boat up on saw horses or blocks and adding just enough water to fill the bottom of the floor. Lay underneath and look for where the leaks are coming from. Mark the leaks with a marker. If the leaks are coming from a rivet, you can try to change out the rivet with a stainless steel bolt, washer and nut. Use a marine silicon sealer between the rivet and the outside of the boat by filing the hole with sealant before inserting the bolt and tightening down. If it is welded you can have the crack or hole welded.

Well, I ground the boat down to the rivets and bare metal once again just like new almost. I've tested an area with the bed liner material and it seems to bond fairly well. Before I put the coat over the whole thing, I need to look to see if a primer might be necessary. If not, it will be full steam ahead with this project using bed liner. After hours of research, and for as many little leaks that I have, this seems to be a viable solution for this boat. Hopefully one gallon will do the job for the coating, we'll see how it goes!

I will keep you guys updated whether either good or bad outcome.... I should snap some before and after pictures and post up if you guys think it might help others or if your curious yourselves??

I do however really appreciate all the input from you guys... I usually just kind of browse and sneak around in here and read the posts, and I enjoy reading what everyone has to say on about every subject.

Thanks everyone and ya know, spawn is right around the corner!! ;)
