I have some GRP Plastic Daggerboards with various chunks and flakes of the white coating damaged. Any ideas as to what the paint is Polyester Gelcote ? Something vinylester or an epoxy The quality of the bond makes me lean towards Polyester Gelcoat
Thanks That is a difficult way to do it Marine tex is notoriously difficult to work with
If the board is made with polyester gelcote you can do a complete repair with gel cote maybe add some microspheres to increase flex and damage resistance.. The boards I have are older and have GRP molded in the handle. For go fast racing shape in important over finish I have had great results with rattle can white paint fron HOME DEPOT LOOKS LIKE STORE BRAND
I have the Intensity Sails daggerboard - when I did minor repairs, I just used WEST or TotalBoat epoxy, thickened a little bit. Sanded back to the original foil shape. And like you said, then just used white spray paint from a big box store. Close enough in color I don't think the fish that see it can tell the difference.
