Hi, thanks for sharing all your restoration info with the forum.
Here's my question. I have a 1974 Starcraft Starchief which was a salt water boat for the 1st 15 years of its' life. The aluminum hull is painted with dark blue interlux above the water line and dull red bottom paint below the water line. Now, I keep this boat on a boatlift so it is totally out of the lake almost all the time. What I want to do is to paint the hull all white, both above and below the waterline.
In the past I have simply sanded an aluminum boat with #50 grit sandpaper on a finish sander, and then brushed on one coat of Rustoleum white primer, followed by one coat of semi gloss white. Rustoleum paints run about $8.00/qt and are traditional oil paint. What's the big difference between brushing on traditional oil paint and using the Interlux or Pettit brands, which I believe are not the same, at all. Is it correct to say that they are two-part paints, sort of like an epoxy, which need to be combined and then applied within a limited time?
