Apache9, I did mine with POR15 but I did blast mine. I love the stuff. It brushes/flows very well and does give you some "body" to fill up any rust pits.
FYI-- rather than open and expose the to air I just drill a 1/4" hole in the middle of the can and pour out small amounts at a time. I stick Duct tape over the hole. I have been using out of a can now for over a year, as I do small stuff, and it has not dried out any yet. If you pour out to much at a time it will actually start skimming on you before you use up what you pour out. So, a little trial and error will tell you what you need to do. I also buy me up several disposeable cheap bushes and if one gets to stiff I just toss it in the trash can and use another.
As Jock says, wear gloves....and the worst clothes you have. You'll find out why

It may help to keep a small fan running to get rid of the fumes and give you fresh air. This stuff will coat your lungs if your not careful.
Let us know how you like it... and you can see my chassis on my photobucket.
EDIT:...sometimes a bristle from the cheap brushes will come out and stick to the chassis. I don't even bother with them most of the time. In the end it just doesn't bother me...and who will see it!!!!
