If your currently don't look like Popeye, you will be when you're done with 
this procedure. RumRunner had the same proplem with her otherwise gorgeous hull 
this spring after having much work done to her bottom. I used a three step 
procedure using McGuire's products. I started off with the #49, heavy duty 
oxidation remover with a wool superbuff compound pad on a 1/2" electric variable 
speed drill. After that I used #45 and then finished off with #56 which is 
almost pure carnuba wax. She looks great six months later. The trick is to be sure 
to use the oxidation remover (I used it twice) to get rid of the white stuff 
and be sure to follow thru with all three steps. 
I wasn't kidding about looking like Popeye when you're done, this is really 
hard on the arms, especially near the bow where you are holding the drill at or 
above you eye level.
Good luck and have plenty of rum on hand for the pain. I am available for any 
further questions regarding this procedure as I am a certified sore arm 
professional. CSAP
