Good to know. I used POR15 on a 67 Cutlass,but would not spray it because of the hazards. Shelf life after opening is a problem. The paint seal between the can and lid was stronger that the can. When I started this current 38 project I bought some small cans of POR15 for the critical areas and primer and Van Sickle enamel (with rust Arrestor???) for the out of site areas. I'll give this Zero Rust a try. We tried a lot of stuff on gensets and boilers we had peirside throughout the Navy and good old Rustoleum worked darn near the best. The red oxide primer has fish oil in it! We worked a lot with the engineers at the civil engineeering command and they found nothing better. Primed, coated with a flat (high solids count) and then a top coat of shiney stuff.

Good luck with your project!
