Has anyone used it? If so what are you thoughts and how do you apply it?

Yes, I've used it.

It's great stuff! It actually works as advertised. You can simply brush off rusty areas, then paint with this stuff and it's sealed in a steal-like caccoon for life.

It's as hard as steal. I accidentally got some on a nut and couldn't remove it with a hammer and chisel!

It's not pretty, and not UV stable (it fades) so if you apply it to say a frame. You might want to top-coat it with the appropriate chassis black. To top coat it you've got to either top coat when it's still tacky, or use POR's special primer on top of it before top-coating.

I recommend you get some of their special solvent because I found it the only thing that would effectively remove it from your skin (and then only within the first hour). You can also get a good solvent for cleanup, but you'll want their special stuff for the 'real' cleanup tasks...meaning your skin, and if you want to reuse a brush you need to clean it in the good stuff too.

I applied it with a brush, it has nice flowability and brush strokes never remained. I just disposed of each brush upon completion. I used it for my frame, and suspension parts as well as the inside floorboards that wouldn't be seen.

I didn't use Por 15, but here is an alternative if you are coating the underbody.
I took my car and had it sprayed with a rhino liner style bed liner. It turned out great. I am not sure what parts you are coating exactly.

I used it a long time ago. Make sure whatever surface you are applying it too is clean!!! And use the metal prep that is comes with, because it needs something to grip onto or it will flake! Thats what happened to me. I also put the POR down, then topcoated it with just a gloss black.
As far as how it stands up to driving and a beating, I dont know, it was on the car while I pushed it up and down my driveway for fun.

Tim brings up an important point of clarification....

If you are putting it on clean/smooth metal you'll want to apply their metal prep first, and perhaps even scuff it.

If you are applying it to an oxidized or rusty surface, simply wire brushing it will be all it needs (unless it's all greasy).

I got the car back from the media blaster, I had them blast the whole floor of the car, bottom and top, from trunk to firewall. They used a more abrasive matierial that made the metal feel almost like sand paper. They said it will make paint stick much better.
I want to cover the bare metal before it rust but i have to replace the front section floor pan. Should I wait until i cut and weld in the new peices? Im afraid if i use POR 15 and then cut out the pan then replace it, then repaint that section, i will have problems cutting through the tough paint.
