[QUOTE="dearl, post: 468212, member: 1760"] Kill the corrosion before you do anything else. The pitting you see will have a white powdery dust in or around it, this is caused by water being trapped between your old transom wood and the aluminum. Mix a solution of 50% muriatic acid to 50% water, work it into the pits really good with a stainless wire brush, rinse well with plenty of water. Don't let it stay on more than a few minutes at a time. If your unsure that its rinsed well enough, you can mix baking soda and water and apply to the area to neutralize any left over acid, then rinse with plenty of water. Let it dry, fill the pits with JB, sand smooth, then primer with self etching primer. No need to paint unless you just want to. Will probably do more harm than good if the paint doesn't stick, it will trap water and cause more corrosion. [/QUOTE]
