Hey Wrvond,
I hate to admit this but I haven't used the rubbing compound yet. I have however been over the boat with 800 . I started with 400 in the more oxidized areas and went to 800. Next I'll go with 1500 then the rubbing compound. Although my boat is a 1996 the gelcoat was not that bad. It did not take too much effort to get the oxidation off. Along the way I noticed several spots on the gelcoat that are chipped and need repair. I'll post some pic's once I get off my duff and get this done. lol
