How much pressure do you apply to a rotary buffer while applying compound? I have some decent oxidation I'm trying to get rid of and polish up the boat and don't want to damage the gel coat.

Not much pressure, but I can't say I know what I am doing either. Better safe than Sorry. What I have had good luck with is Wet sanding it with 1200 to 1500 paper first then buffing with rotary and wool pad with buff Magic. I have had good luck and a finish that last longer.
 
Thanks, I'm thinking of trying a heavy compound before going to wet sanding.
 
Very light pressure, let the machine do the work. If that doesn't do it, start with 2000 grit sandpaper and work your way towards heavier sandpaper (1500-1200, etc) will do the trick, then use the lighter grit to get out ultra fine scratches, then buff and polish. Use good wax or sealant of your choice to protect all the hard work. Good luck, Matt

Agree. The weight of the machine should do it. Anything more and your gonna burn it trying to bring it back. If that's the case light sanding first.
 
I use almost zero pressure. I'd rather go over it a few times than burn it... I had horrible oxidation and now shines like a slightly included diamond.

Looks good. I tested a spot on the bow and she cleaned up nice using Meguiars fiberglass restoration. I only used the oxidation remover and polish with no extra pressure. I'll post some pics once I get some more done. I'm planning on removing all of the snaps so I can use the rotary buffer instead of doing the gunwale by hand. It really is a pain to go around all of the snaps.

Depending on the amount of oxidation it may take several tries. I've probably buffed mine 3-4 times in 2 years. I use 3m compound then the finesse IT II system and follow with a hand wax each time.
