RUST ! AGH !

I don't know if this is the right forum for this, but since this is all about chassis maintenance, I thought I'd give it a go.

Has anyone ever heard / used a product called POR-15 for rust prevention? Can anyone speak about thier experiences with underbody / lower door rust prevention. I have some rust that I would like to work on, and take measures to prevent more rust from taking hold.

What does anyone here do / use for rust issues.

Any advice would be apprecieated.

Thanks
