Has anyone had any success with any of the "CLEAR" coatings such as Aurora's VS721 Bottom Wax or even their Repelin? I have never had any opaque antifouling paint on any of my running gear, thru hull fittings or trim tabs. Used my last can of TBT clear spray from Tempo last year. I really don't want to put conventional black bottom paint on any of these parts. I thought I read somewhere that someone has just developed a clear put I can't find the article.
