What is 3M? www.3M.com Goto a marine suplyer and ask for it by name, unless your missing the bottom of the boat this stuff will seal it.

stevston marine should have it

best would be to layout and rivet a .040 aluminum doubler over the hole sealed with proseal 870 available at aviall. B 1/2 will give you a half hour pot life and B2 will give you two hours, 1/2 should be all you need if you work quick.
If you need more info Pm me

Sikaflex is specifically made to do that job (made by Sika). The tube will say LOT291 on the label. It skins over in a couple hours but takes a lot longer to cure fully. Local humidity makes a difference as it needs moisture in the air to cure. I assume it's just a popped rivet or seam, but if it's a hole then a doubler as Gnarly suggested would complement the Sika as well. Rivets and seams are a problem in most older 'tin boats'

The equivalent 3M product is called 5200. Sika's easier to work and doesn't turn yellow in the sun but is a little more $$ than 5200. I can get it locally at the building supply.

CHECK THE EXPIRY DATE ON IT !!!!

I've probably got a part tube floating around here somewhere if you just need a bit and you're not picky about color.

I agree with Gnarly's suggestion, patching it is the best way to fix it if the holes that big. silicone or Sikaflex will wear out over time and the whole will increase if it's in an area that gets alot of beating on it. I use a product called Duraglass at work for filling small holes and cracks. It's supper durable and easy to sand too. If you decide to patch it and use pop rivets cover the rivets and seem with duraglass, Rivets don't last long in a marine enviroment!

Hope this helps abit, good luck.
