por15 ???
how many gallons does it take to do a frame springs axles etc also it says it will brake down in the sun to top coat it. I know they use it on many kinds of projects does it need to be top coated when it is under your truck protected from the sun or does it need it any way for looks

You can probably get away with 1 quart if you spray, 2 if you brush apply. If its only on the frame and suspension I wouldnt be to concerened about the UV damage, but its just as easy to apply a top coat of chassis black or even something like Rustoleum. Just apply while the POR is still tacky for best results.

Spraying it requires a forced air respirator, that stuff is NASTY to breathe, so I'd go with the brushing. I did my 67 frame, axles, and assorted brackets with 2 quarts. A little goes a long way. Get a ton of sponge brushes, you'll need a lot!
The only spot that may be affected from the UV rays is between the bed and the cab,where the sun may hit it, or through the wheel wells. I went ahead and shot over my POR-15 with Eastwoods 2K chassis black. Just had to scuff it up, and shoot it. Came out great, I highly recommend it!

I dont understand why the need for the forced air respirator,(I know they say it must be used for spraying, but how many body shops have forced air respirators?) I sprayed it with a regular respirator with a particulate and organic vapor filter and nothing got thru. But then I also has an exhaust fan blowing as much as possible out a window as well.
As long as you clean up the gun immediatly after using it it will not screw anything up.

Its on the can of POR15 as well. They were just covering their butts by saying that. It is nasty stuff, but as long as you wear long sleeve shirts and jeans, a hat wouldnt hurt either and a respirator with particulate and organic compound filters I think you'll be fine. Its not like you are working with it all the time. I've sprayed enamels that are probably worse than POR15 as far as overspray and OC's

I actually wore a heavy paper coverall from here at work, and a full face mask, with a cooling helmet on it. Worked like a charm.

Everything says "supplied air respirator" now because there's no way to tell on those disposable organic vapor respirators when the cartridges are bad. 3M used to say a week in typical spraying. But is a week of typical spraying a painter at a bodyshop, or you guys that do it every now and then. So, everything now is supplied air......to cover butts.

As for the gun, I'd go ahead and pick up a cheapy one. Why take the chance of ruining your good gun. I keep a cheap gun around anyway for spraying heavier paints like rustoleum.
I liked brushing the POR on better than spraying and those sponge brushes work wonderfully. You don't end up with brush hairs in the finish. The finish smoothes out as it dries.
