For those of you not addicted to the "Do it yourself" approach, I
recently had my 1984 Cobra (aluminum) trailer painted by Miracle Auto
Paint. The trailer paint was in terrible condition, flaking and pitted
from living under a tree for several years. Miracle did the whole job
for $1200 including prep, epoxy undercoat, acrylic auto paint, and
detailing.

The trailer looks fantastic, and while I would not want to make an
andorsement, I had my Volvo painted by them about three years ago, and
the paint job has held up very well.

Post-paint waxing is important.
