IMHO the best web site for autopainting is http://www.autobodystore.com/cgi-bin/config.pl?index
The guy that runs the site has done a direct comparison test between POR and Zero Rust. Considering only protection, Zero Rust was better. Then pile on that it's cheaper, comes in quarts or spray cans, and is easier to apply. Made the decsion simple for me. More info at
http://www.zerorust.com/

 

Hey, there is nothing wrong with zero rust, and if it is more convenient and cheaper, go for it. POR 15 just seems to be the choice of most Mustang restoration guys.

 

Thanks! Will post some before/after pics as soon as I get to the after.
