Anybody have ideas how to restore a damaged area on an aluminum mast? Somehow about 2ft. right near the top got chewed up. Didn't notice it till we derigged and took our 216 home. Only thing I can think of is that during some wild weather our's and it's slip neighbor, an O'day, must have rolled and the masts slammed together. That ripped up section should be sanded smooth and then coated? With what? Boat's only a year old,so appearance is a factor. Help! Thanks!
