I have an anodized mast on my SJ21. During the past 28 years of its life it has seemed to stand up well except for the many scuffs and scratches.
Is there any way to refinish it i.e. re-anodize it myself?

Thanks,

Nicolas

Upon investigation I have found that anodizing shops can''t handle the length of most masts. I''ve had pretty good luck by wet sanding with 600 grit to clean the mast up, then giving it a good coat of Penetrol. Does a good job of protecting from the elements and gives a nice gloss to it. Hope this will help you.

I just refinished my mast. I went with awlgrip. The original paint finish had lasted 18 years which seemed fine to me. I had the yard actually do the spray job which was not that expensive. I will probably roll and tip the boom and spin pole once I get my workshop set up at the new house.

We redid our 20+ year-old boom with 2-part poly from Interlux (it appears easier to apply by non-pros than Awlgrip). We have been quite happy with the results, applied with a 3" foam roller and brush (tipping not really required). We''re waiting for the mast to get a bit more beat up before tackling that 65''project.

I looked into powder coating... went kind of nuts on it on my 22'' MacGregor... had the windows, all the cleats, even the anchors, powder coated copper... looked beautiful, and still holding up well after 4 years... was about $130 for about 2 dozen pieces of hardware
but as stevethompson said about anodizing, most shops cant handle the length - I think the standard oven is about 14'', and Ive heard rumours about open-ended ovens which can handle things like masts, but have yet to find one.

I purchased a Lindenberg 22. It is 20 years old and the paint on the mast has bubbles on it. The paint will flake off in these areas very easily. A wire brush will clean up these areas just fine. What is the best method to get all this old paint of the mast and clean it up?

Once all the paint is off is painting the mast my only option or is there a wax/finish I can put on the mast to keep it the natural aluminum color?

If your mast was originally painted and you sail in a salt environment then you are pretty much committed to painting the mast. You can chemically strip the mast but need to find a stripper that is safe for aluminum. I like the strippers that use a paper mebrane to retain the moisture in the stripper and allow you to remove paint intact. If the paint is badly oxydized then you may be able to sand it off easily. The steps for pinting aluminum are not that difficult but there is a definite sequence to follow if you expect to get a durable finish. I believe that the Interlux (International Paint) site has a good discussion on this.
