My 20 year old H33 mast is beginning to show it's age. It has the original white coating looking pretty worn in spots. Any suggestions on repainting the white mast? Looking for what type of paint; brand of paint; spray or roll? Ken Palmer S/V Liberty

mast painting
Ken, I have the same job to do. My 79 H33 has the mast down for the first time in a very long time and I am rewiring and will repaint it. I notice that the manufacturers of the two part polyurethane enamels recommend the paint for this duty and this is my present plan, rolling and tipping, but I am very interested in other replies that you may get.

Some say: Don't bother
There are some who claim that you don't need to paint an aluminum mast. Here's a post, in another sailboat forum: http://www.yachtingnet.com/community/forums/sail/3449/0.html All my spars were painted when I bought them, and stayed that way while I had them, so I cannot comment on the idea of "going raw." I have noticed that my current mast has some spots where the paint has rubbed off, and the mast seems none the worst for it.

power coating
Mine is an 81 H33 and like all of yours, my mast and boom are starting to show their age. Though I'm sure it is much more expensive I'd probably look into having the spars powercoated. But than I'd be into the "might-as-well-as" theory. This means I might as well fix/rework everything on the spars while they are down. Some companies do this as a package, possibly JSI in St. Petersburg FL. Good luck, I'm curious how it'll all turn out.

Power Coating?
I am not familiar with that term. I have heard of electrocoat. "The fundamental physical principle of electrocoating is that materials with opposite electrical charges attract. An electrocoat system applies a DC charge to a metal part immersed in a bath of oppositely charged paint particles. The paint particles are drawn to the metal part and paint is deposited on the part, forming an even, continuous film over every surface, in every crevice and corner, until the coating reaches the desired thickness. At that thickness, the film insulates the part, so attraction stops and electrocoating is complete. Depending on the polarity of the charge, electrocoating is classified as either anodic or cathodic." (copied from http://www.electrocoat.org) That would take a very large vat for the paint, plus cost of shipping, etc. I think I might go with the single or two part epoxy paint. I have been thinking of buying a Wagner paint sprayer for the VC17 antifouling paint, so maybe I could use it on the mast also. Any hints on what Wagner sprayer to use on these paints?

powder coating
powder coating is another type of industrial coating. Both powder coating and electrocoating are very specialized and would be cost-prohibitive. So the alternative is 2-part epoxy, done by you or a contractor. Myself, I'd live with it.

Two part LPU
Two part LPU (not epoxy) works great. I used Awlgrip, ten years ago. It is much better than the original. Take the time to remove and rebed all the fittings. Check the winch bases for corrosion. You may spend quite a bit of time at this but it is very worthwhile. A good mast paint job will make the whole boat look better. LPU can be sprayed or brushed.Awlgrip, Sterling or Imron will all give a good result. Good luck. You may find the best result will come from doing all the prep and having a pro come to spray the paint.
