DISCLAIMER: I have never used a DA on a boat. The below is for wash, wax, and interior.
Best wax I've found. (I follow the 925 with Babe's spray wax if there are any spots that just don't quite look/feel right and it's a great LSP) http://www.amazon.com/Collinite-Liquid-Fiberglass-Boat-925/dp/B000E48H9I
Best products I've found. (Minus their soap. It seems to leave a film behind that dries to a haze. Meg's makes a good wash if you can find it. Usually at Walmart or Academy) http://babesboats.com/
You'll want lots of brushes, good towels, and a vacuum with a few attachments.
Also, pack food beer water and music.
