hey 69 - - Thanks for sharing all of this information. I stayed up half the night reading about all of this. I think I am gonna do some experimenting with this too.It would definitely be worth the effort for me to try this.

I am wondering if someone in the U.S. who lives close to Canada could just buy some of the Tremclad and test it against the Rustoleum. Maybe someone in Michigan or NY or Washington state?

Do you think the scratching has anything to do with whether it is painted directly onto bare metal or over paint? Would it dry any faster if it was on bare metal? Just curious. So, you're saying it is approximately 5 months to toally dry? Thanks again for all of your help. - - Rob
