Aluminum repair

[Tim Frank]

I have a small problem with the exterior aluminum skin as I repair the wooden transom insert.
There are two areas of pitting on the inside surface where there was leaking and rotting of the adjacent wooden layer, the size of a quarter, and one of these actually is deep enough that there are a couple of pinholes right through the skin.
The remainder of the aluminum is near-perfect and there is no structural compromising whatsoever.

Anyone have an opinion on the best way to fill these two small spots?
I have thought of simply using a high quality silicone seal like a drywall nail hole filler, or an epoxy "peanut-butter" mix the same way.

Any suggestions welcomed. Thanks.

I Agree with Bondo epoxy or Gluvit will do.

I would use Marine Tex. I have seen fuel tanks, engine blocks, and manifolds repaired with marine tex.

I filled a gouged out place with some of the metal epoxy putty made for metal. It filled tight and was sandable. Then I painted it with a good coat of epoxy bathtub restoration paint. No way will it ever leak.
