Coating aluminum boat

[Roberthill]

Riveted aluminum boat has slight leak , what is a good coating? I've asked this before and used what was suggested but this is another boat and I can't remember what I used but whatever it was it worked great .
Thanks for your consideration.

First I'd recommend "Re-Bucking" the rivets in that area. If this isn't successful, then "Gluvit" or "Coat-It" is the next best thing.
