There is a faint light blue color beginning to appear in the non-skid areas on the bow on our 1989 440. It appears that the gelcoat (or is it paint) is growing thin and the fiberglass resin is starting to show through. I have seen this on the bow area of other older OAs. Does anyone know for sure what's happening, and a recommended fix....I guess either more gel coat or paint? Anyone have the color spec? Thanks
