I used Interlux for my boom.
The short answer details ... I sanded to bare aluminum, I used one coat of Rust-oleum clean metal primer (oil based), I put on 2 coats of Interlux Multithane Primer (a 2-part paint), then I put on 4 coats Interlux Perfection (also a 2-part paint). I wet sanded lightly between coats of Perfexion with 400 grit and cleaned with a solvent cleaner. I applied all with a good quality 1.5" bristle brush. The results look great and I am still just hoping that it is chip resistant. Now the long explanation ... Late last summer I bought the old product which was the Multithane Primer and the (Interthane Plus?) enamal finish coat. My mast and boome was black, I didn't think I would sand all the old paint off so I intended to paint them black. I brought the boom home in the late fall and found that the old paint sanded off easily, so when I had a bare aluminum spar, and primed with white primer, I decided that I wanted to have white spars. So I tried to return the black Interthane but they had updated the product to Perfection. This stuff is really expensive (I think I paid about $60 each for a quart of Multithane and a quart of Interthane), so I wanted credit for the old quart. Since I'm a good customer, they listened to me sympathetically before turning down my request for a credit on the old product. They did call the factory to confirm that the Multithane Primer (also the old product) will work with the Perfection without having to start from scratch with a new primer. Since I now had my heart set on white, I was faced with numerous choices in white, but I wanted the color that was REALLY white, so I chose "Snow White". This was $17 more per quart (I paid about $83) than the other white choices, but it was what I had to have. :{ I am pretty sure that one quart of these products is enough to do my mast, boom and pedestal. I am waiting for warmer weather to do the pedestal without removing it from the boat. This may be tricky because it will be outside with no climate control and the surfaces are vertical and irregular. The boom was done easily indoors laying flat. I haven't done the mast and I don't want to do it while it is up. I was going to wait until a winter when I take it down. Now I am considering taking it down this spring since it has been so dry, our lake level is down and we may not be able to splash until it comes up a few feet. We are having a dry spring and it may take a while. Mixing the 2-part paints was a mess and not easily done for the small quantity that was required to do just one small surface at a time. I used small plastic water cups to mix the small amounts and quickly realized that if you leave it in a plastic container for painting, it dissolves the plastic quickly and leaks. So I started to use an old coffee mug (which also cleaned up easily). Acetone was the only solvent I found that would work for clean-up. Those cans with the lips that catch the curing agent and paint are really messy and there should be a better way. :{ The problem is that you don't want to mix more than you are going to use because the stuff is really expensive to waste. I didn't have any system for turning the boom over before it cured so I was jsut doing one side at a time and it took a long time. Also, the fumes are really noxious and it was hard to avoid getting a headache (I'm sure I killed enormous quantities of brain cells). I tried a mask but that seemed to make the concentration of fumes even worse. Open windows were my only solution.

frmreilly , right indeed
the reason i need to paint the mast is it was originally (i think) painted and now looks all nicked up. so i needed to change the transducer and some light bulbs so it is time to do it. mike
