I recently purchased an 81 Mac 25, and an 87 M26D. Masts on both have pretty much no anodize left along with small pits and many dings from use. The last time I painted a mast was on my P-Cat (1983) and it held up very well for years before I sold it. I used a catalized Polyester primer that is still available. Unfortunately the original Imron that I used is no longer available. Any ideas for best currently available paint?
