There is provided a surface composition for reducing degradation and fading of surfaces subjected to extended periods of submersion in an aqueous liquid. The surface composition comprises at least one clear barrier layer and at least one under layer, wherein the clear barrier layer is in use, disposed atop the under layer and in contact with the aqueous liquid whereby the clear barrier layer protects the structure and appearance of the under layer. The surface composition is particularly useful in applications where the surface is subjected to extended periods of submersion in liquids containing hydrolyzing or oxidizing agents, exposure to ultra violet radiation, or combinations thereof, whereby the clear barrier layer provides structural protection against degradation from chemical attack and from fading due to UV exposure. There is also provided a method of manufacturing a boat or other watercraft surface composition.

1. A method of manufacturing a surface composition for reducing degradation and fading of surfaces subjected to extended periods of submersion in an aqueous liquid, the method comprising applying a clear barrier layer to a mould, permitting the clear barrier layer to cure and subsequently applying a colored under layer to the cured clear barrier layer;wherein the clear barrier layer is in use, disposed atop the colored under layer and in contact with the aqueous liquid, whereby the clear barrier layer protects the structure and appearance of the colored under layer, wherein-the clear barrier layer comprises a clear polyester gelcoat, and wherein the clear polyester gelcoat comprises one or more phthalate containing polyesters, vinyl containing polyesters or methyl methacrylate containing polyesters, and wherein the colored under layer comprises one or more polyesters, vinyl esters or terephthalate based resins, and wherein the colored under layer is free of particles and chips. 2. The method according to claim 1 wherein the mould is that of a watercraft. 3. The method according to claim 2, wherein said watercraft is selected from the group consisting of a boat, ship, canoe, kayak, raft, barge, catamaran, yacht, hydrofoil, windsurfer, surfboard, water skis, jet skis, underwater robot and seaplane. 4. The method according to claim 3 wherein said watercraft is at least in part comprised of fibreglass reinforced plastic. 5. The method according to claim 3 wherein the composition further comprises one or more UV inhibitors, absorbers or stabilisers. 6. The method according to claim 3 wherein the clear barrier layer comprises one or more UV inhibitors, absorbers and/or stabilisers. 7. The method according to claim 3 wherein the clear polyester gelcoat comprises a phthalate containing polyester. 8. The method according to claim 3 wherein the clear polyester gelcoat is derived from an isophthalic neopentyl glycol. 9. The method according to claim 8 wherein the clear polyester gelcoat is derived from greater than 70 mole % neopentyl glycol based on the total mole % of dihydroxy compounds in the polyester. 10. The method according to claim 3 wherein the barrier layer comprises a triazine based LTV absorber. 11. The method according to claim 3 wherein the barrier layer comprises a hindered amine light stabiliser. 12. The method according to claim 3, wherein the under layer comprises one or more epoxy vinyl esters, brominated epoxy vinyl esters, novolac epoxy vinyl ester resins or elastomer modified vinyl ester resins. 13. The method according to claim 12, wherein the epoxy vinyl ester resin comprises a bisphenol-A epoxy vinyl ester resin. 14. The method according to claim 3 wherein the under layer further comprises one or more metal promoters. 15. The method according to claim 1 wherein the clear barrier layer comprises one or more metal promoters and is free of cobalt promoters. 16. The method according to claim 15 wherein the one or more metal promoters is selected from the group consisting of zinc octoate or potassium octoate. 17. The method according to claim 1 wherein the clear barrier layer comprises mixed metal promoters and is free of cobalt promoters. 18. The method according to claim 1 wherein the clear barrier layer is clear prior to application and remains clear after application and curing.
