Thanks Mike!

What primer did you use? And I know we don't have the exact trailer but how much did you use, if you rememember of course...

Thanks again!

I applied two coats, one per day for two days, and used around one gallon I think when mixed with their thinner. I did not use a primer, it is an old fiberglass trailer that did not need it. The existing finish had worn evenly partway through and you could just see a bit of the glass fibers sparkling in the sun. I cleaned it well before painting it. Your metal trailer will need a primer though if you strip it down to bare metal. Check for primers in the posted Jamestown link.

BTW I met a pilot once that used this type of one part polyurethane on a sailplane that turned out really nice. I do not remember if he used a roller though.
