Paint for bottom of bilge

2 posts in this topic

The part I an concerned with is the keel sump. This portion is continuously wet. It is currently gel-coat. My concern is alkyd enamels may not be the best choice for this section. Would thorough cleaning, and sanding with scotchbrite pad, and painting with total boat 1 part epoxy perhaps be a better choice? I will also be re-positioning some switches, and bilge pump. What would be the best choice for filling old holes?

A good cleaning and sanding with 80 grit then clean with acetone should prep it well for paint.  I'd recommend Totalboat Total Protect two part barrier coat primer.  This will seal it from water seeping through the gel coat.  Apply about 3 to 4 coats.  Any holes can be filled with Totalboat Thixo two part epoxy.
