I bought my 88 C-22 used so don't know the bottom paint history. I keep her in salt water mooring here in AK all year. Last time I pulled her out, bottom was covered in barnacles that I scraped off. I am planning to bottom paint. Not sure about the epoxy barrier paint issue. What did these boats leave the factory with? Mine is a very good condition blue painted surface. Is this bare gelcoat or was it painted at factory? Do I need to apply any epoxy before sanding and using antifouling ablative?
