Pin hole repairs

[sickshaun]

Hello new here.. Purchased a early model sears and previous owner had screewed wood to back of transome with a hundred screws. Been filling holes for days with welder. Looks really good just when i shine a light behind it theres lots of small pin holes. Do I keep hitting with welder or is there a type of bondo for aluminum that I can spread on there and smoot out prior to painting to seal up all the little imperfections.

I would use a fairing compound. Total Boat sells some good stuff. Those pin holes are called porosity and yes it will more than likely leak. You will have to prime and paint after applying the fairing compound.
