Prep the trailer using an orbital sander with about 180 grit for the chip prone areas and undersides and about 280 for the tops and sides. Wipe it down, I sprayed an etching primer (DP40 PPG) and the next day I used a green scuff pad add some bite and sprayed 2 quarts of single stage GM summit white. Actually used my older siphon feed gun at 40 psi. Fenders I sprayed the same paint and then added chrome metal flake into the first layer of clear and then clear coated the fenders. They look great in the sun.
You prepped/sprayed the trailer with the boat on?
I'm getting ready to replace my bunks with new wood + carpet and plan to do one side at a time, lifting the boat just far enough on one side to remove the bunk boards. Planned on hitting the rust areas while doing it - but based upon your restoration, I might plan on a more in-depth repainting!
