rust proof paint???

[ken ogi <ken@norstargroup.com>]

hello list
i took my roadster apart and found more than my share of rust and some
rots.
i used rust mort and then coated it with epoxy primer + sealer... i
thought this will virtually stop the rust from spreading. well
"virtually" is the right word because i still have areas where the rust
has bled through. now i'm looking at a paint called POR-15.
has anyone ever used this stuff? does it work?
any input would be grateful :)

thanks
