I didn't start out to repaint it but after removing the wood strips on the lid and refinishing them I decided to go all the way. I was going to color match it to the bike until I found out what the supplies were going to cost. I couldn't see spending that much money to repaint a $600 trailer.
After taking the trailer all apart I dry sanded it with 320 grit and then wet sanded with the same grit.
Here are some pictures as I proceed.
