Either Devcon or 3M 5200. Avoid the welding if just a pinhole. As the area
around the weld gets affected, and has a tendency to crack ir strained.

I recently purchased a used aluminum Jon boat. It has a pinhole about 6 or
8
inches away from the drain plug hole. If a person was inclined to try and
repair this pinhole, what would be the best method.

I have used Devcon (an aluminum putty) for other repairs (not on boats). I
also have access to aluminum welding process.

Any advice would be appreciated.
