Others have too many fillers and will leave your job looking crappy in a few weeks. You will need 4 stages(wool pad + compound, low cut wool pad + imperial, and then waffle pad + Perfect It finishing glaze then wax). Probably 6 if you sand. You can get different cut wool pads too which should further reduce need To sand. Go to a local automotive paint & body supply store and get you some 3M compound, 3M imperial glaze and some perfect it finishing glaze, buffing pad and a pack of waffle pads. They should help you with what you need....maybe a Velcro pad for your buffer too. Makita makes a great variable speed buffer if you need one. Cover the interior, buff in shade, and i would mask off rub rail etc so no compound can get in crevaces. Id even throw sheets over rails on trailer it will make life easier when cleaning.
Feel free to pm me any questions.
This is your answer. Once you complete this I would then throw a coat or two of the 3M Marine Wax. I can get you the 3M UPC codes and part numbers for all of these in the AM. I will also check to see if j have it in my sample stock, If I do I will send it to you if you cover shipping. The stuff is not cheap.
