I have used POR 15 a couple times. I am not impressed especially about the costs. There are now better products out there. There was a paint test some fisherman did on a set of motor mounts on a salt water fishing boat a couple years back. He painted one side with POR 15 and the other with????? A year later he posted pics and the POR failed and the other stuff did not show any signs of rust at all.
I wish I could remember the name or had a link.
A lot of freakin help huh?
