3M Products
I have had two boats, one a 1978 and most recently a Catalina 25-1989. On both I made them look new and shiny. Wash your hull, I use tide laundry soap. Use 3M Heavy Polishing Compound. Put on with a buffer (wool pad) working a two foot sq area at a time, keep the pad clean by spurring it up with the reverse end of a pair of pliars. You can be aggressive. Wax it with 3m Ultra Performance Wax (paste-carnuba). It goes on by hand and I polished it off with a clean wool pad, you have to keep the speed down on the buffer or it will get hot and gum up. I put four coats on the boot stripe and three on the hull and it looks great, a bright deep shine. If the gel coat has darkend/oxidized due to sun you can sand with wet/dry sand paper 600 grit, then go with the rubbing compound and wax. Test the polishing compound first, the transom is a good place to start and learn. Hope this helps
