Obviously a 92 model has some definite UV damage and at varying levels for each boat depending on hows it was used, stored and exposed. The best solution is to very lightly wet sand the top finish with 1500 3M sand paper. Then repolish the surface area. Followed with another wax coat. Polishing alone sometimes will not remove that residue from the top layers, which is dead gel coat. Sanding should do so, and be cautious of the small stripes on your deck. Those have little protection and should be taped off to prevent sanding the outer layer off. BCB
