A little intro. I recently bought a 1961 Alumacraft Queen 16. And I wanted to get some info on it so I tested Alumacraft customer with the HIM. And within two days they got back to me with everything I wanted to know about this boat. They even sent me a picture from a sales brochure of the boat. I know this is old news to most of you,but I wanted to in a plug for these guys, they do great work. This may or may not be new to you guys, but I was trying to remove the oxidization from the hull. I tried fine grit wet or dry sand paper, a buffer, and scotchbrite pads. But it looked liked spider webs everywhere. Then I tried it by using scotchbrite pads trimmed to fit on a palm sander I have with a hook and and loop shoe. It works great. There are no directional sanding scratches and it gives a nice satin finished. FWIW
