hi Azcat. I clearcoated my mast, After it was in the same state as you have described. I used 2 pack clear coat (norglass), And painted it with a brush, Too lazy to spray it. (2 coats) The mast came up really well, From 3 feet away it looked like a new mast, When you got close you could see the brush marks and some of the blemishes that i could not get out with out really sanding the mast heavily.
I did have an email from Saarsberg mast somwhere, And he said only use 600 wet and dry on the mast, And don't sand into the carbon.
Hope this helps
