I live on the coast (less than one mile from beach:angryfire
I have used SKYCO OSPHO,SEM RUST-MORT,POR15 METAL-READY,CORROSEAL, they seem to be the same.The CORROSEAL I just started using and I like it smells like elmers glue not rotten eggs. And it's thicker than the rest. so what do you use and why?
