Quote:Solotripper- hows does the stuff hold up with UV?
The website explains it better than I can, but the quick answer is that IF the area is exposed to the sun, you need a top-coat dressing over the Por-15, which will take care of the UV problem.
You need to use the materials they sell to prep metal, then Por-15 and top coat as called for. I'd use the semi-gloss chassis top coat on the trailer.
My brother turned me on to this stuff. A friend of his uses it for restoring cars from the frame up. He ( my brother's friend) was skeptical at first. He bought the little starter kit, and painted a chink of rusty scrap metal.
After it had cured, he tried every solvent that would dissolve/ruin normal paint. Nothing worked. To clean it off, he had to sandblast it !
They caution you to wear latex gloves and avoid contact on skin. Once it dries, only time will remove it

They sell cheap disposable brushes, it's not worth trying to clean good ones.
They make a fire resistant paint manifold paint and other specialty products for marine/home/auto. They have a wheel dressing that comes in a can. Unlike the stuff from the auto stores, this will last ALL summer and look like brand knew.
I highly recommend it. Buy a starter kit, and see for yourself.
