Perfections Detail Posted February 27, 2011 Share Posted February 27, 2011 All of a sudden I'm getting more and more boats, do opt products work on gel coat? Which would you recommend, I have poly seal, ocw, and opti seal? I hear marine grade polymer is the same as automotive grade polymer. Has anyone had any experience using opt products on fiberglass or gel coat? This would be a mix of fresh water and salt water environments. Thanks for any advice Link to comment Share on other sites More sharing options...
