1. In a method of finishing a surface comprising the steps of applying at least one sealer coating composition to form a sealer coat and/or at least one top coating composition to form a surface top coat, the improvement which comprises using an improved sealer and/or top coating composition comprising a film-forming resin composition and a sol gel processed ceramic grain in an amount effective to impart abrasion resistance to the surface finish.2. The improved method of claim 1 wherein at least two sealer coats are applied to the surface before the top coat is applied.3. The improved method of claim 1 wherein the coating composition for the top coat comprises a film-forming resin composition and a sol gel process ceramic grain.4. The improved method of claim 2 wherein the coating composition for the top coat comprises a film-forming resin composition and a sol gel process ceramic grain.5. The improved method of claim 1 wherein the sealer coat or top coat is formed using a coating composition wherein the film-forming resin composition comprises a thermosetting resin.6. The improved method of claim 1 wherein the sealer coat or top coat is formed using a coating composition wherein the film-forming resin composition comprises a UV-curable resin composition.7. The improved method of claim 6 wherein the UV-curable resin composition comprises olefin functional monomers and olefin functional oligomers or polymers.8. The improved method of claim 7 wherein the olefin functional oligomers or polymers comprise polyurethanes.9. The improved method of claim 1 wherein the thermosetting resin comprises epoxy resin, a polyurethane resin, a polyester resin or an acrylic resin.10. The improved method of claim 2 wherein the thermosetting resin comprises epoxy resin, a polyurethane resin, a polyester resin or an acrylic resin.11. The improved method of claim 1 wherein the sol gel process ceramic grain in the sealer coating composition comprises alumina.12. The improved method of claim 11 wherein the sol gel processed alumina forms about 1 to about 60 percent by weight of the sealer coat.13. The improved method of claim 12 wherein the sol gel process alumina forms about 1 to about 15 percent by weight of the top coat.14. The improved method of claim 1 wherein the surface is a wood surface.15. The improved method of claim 1 wherein the surface is metal, plastic, paper, composite fiberboard or vinyl.
