Nothing is your best option.

If rivets are leaking then fill it with water and see which ones it leaks out, mark them all then drill and refit the rivets.

use crc brush on under sealer from repco. if you are planning on using the boat on a river or lake it should be ok to buzz around in. remember life jackets.if you plan on going to sea forget it, sell it for scrap and start saving for a new one. i may sound like a harsh a-hole saying that but people die every year in boats that were not sinking when they set off.

It should be sanded with 150grit, and heavily scothbrited around all the riverts by hand.

Then acid washed with a suitible phosphoric acid and thouroughly rinsed with water.

Then you MUST apply something like this. http://www.altexcoatings.co.nz/vdb/document/1021 Once that etch has set the chouce of primers and top coats are really up to you. But if you do not etch the aluminum properly as a first coating then you paint will not stick what so ever.

This here is another system that can be used. It is rather pricey though! http://www.pettitpaint.com/default.asp

As far as seam sealant goes. Have a browse through the 3M and Holdfast websites as there's quite a few different options.

more like from nongs that fail to engage a brain that a boat is filling up with water which is why you always carry good communication gear, bailer/bucket etc.

I concur.

The bloke asked for paint advice, not a bloody lecture about water safety!

Hahahahaha good stuff, No but in all seriousness if you want a sealer for Aluminum then you would probably only be able to get it from the U.S. or Canada. sealer for Aluminium in NZ on the other hand is quite commonly avaliable
