POR-15, any experience?

[Roa, Greg]

Hello all,
I'm getting my 4kq ready for a repaint, still....
Anyhow, I think I remember someone mentioning POR-15 as a good rust preventer.  I've got some spots on the underbody that I'd like to use something similar on
Does anyone have any thing good or bad to say about this stuff?  They have a starter kit for $15 I was thinking of getting.
Thanks!
