M_Boats: Gel coat restoration

Hey Skippers, Anyone have experience with M15-23 gelcoat restoration ? My boat previously was a Dream Boat: she sat in the sun while the owner mostly dreamed. My impression is that JM used very good technique/ materials, the damage seems minimal compared to what I’ve seen on equivalent age sun stored boats. So I’d describe the oxidation as light/moderate. I’m looking at a shurhold polish/ buffer. I’m well aware of the danger of over zealous circular polishing, seems more likely with lapstrake hull form. The Shurhold is orbital and smaller. Also would love to hear about nonskid cleaning/ restoration experience. Ed Epifani M15 ‘83, #200 something Sent from my iPhone
