Waxed the camper this weekend. Any tips/tricks for future?

I have a fiberglass sided trailer so I use the same process I used on my fiberglass boat. 3M cleaner & wax. In the boating world the theory is use a quality (3M or Mcquires) buffing pad then you can use a Harbor Freight electronic variable speed buffer, or splurge and get a makita or porter cable. The 3M cleaner / wax takes care of mild oxidation and puts on a coat of wax in one step. After a day of fishing, I was able to just hose off the crystalized salt and fish blood off the boat and call it good.
