If you don't use the special coating over it and under other paints, they just peel off.
For what you are talking about - spot repairs - I'd go the traditional rust converter, primer, touch-up paint route.
BTW - if you get it on your hands you get major staining that lasts for days - don't ask me how I know.

He's right. I did an entire frame up on a 74 Bronco and used POR-15. That stuff is tough as nails but you need to prep it right or it's useless. It's a pain to paint POR-15. For minor repair, go the traditionnal route. I have found that POR-15 is best for anything hidden or underneath. And unless you're willing to shoot it (major PITA), you're gonna brush it or roll it on and it's not going to give you great results as far as finish and you need all those specials paints from the company.
Wear heavy rubber gloves, like kitchen gloves and long sleeves, and a mask, that stuff stinks and gets you high pretty quick... If you get some on your skin, forget about it, don't even try to wash it out, you'll just get frustrated. You're stuck with it for a couple of day so enjoy...

I prefer to be misunderstood rather than having to explain myself all the time...
