Coating a corroded aluminum radar arch


I recently bought a boat from Florida that has a painted aluminum radar arch that has corroded everywhere the paint has been compromised by a stainless fastener. What can I use to remove the corrosion completely. Is there somewhere to have it dipped in a solution in my area? It is quite large, 5' high by 10' wide and 10" cross section. Thanks

Hi, Dennis. Ideally this radar arch should be anodized, but that may be impractical if it's all assembled and welded together, and is impossible if steel or stainless steel items are attached. Second best would be chromate conversion coating.

The plating shop may dip it halfway at a time, or do some touch up with a brush. After having it painted, don't attach stainless steel in an electrically conductive way. Good luck.
