Well I just ordered a pint of POR-15. I'm hoping it's enough for what I want to do. First, I want to undercoat my car, and do the wheel wells and exposed parts of the frame. I also want to do the underside of the hood, under the vents, etc. Should a pint be enough? And also, how do I apply this stuff? Can it be applied upside down, like on the underside of my car, without it dripping and all that?

It's actually best applied with a brush. Yes you can use it in any position, even upside down, but be sure to wear gloves and especially eye protection. I hear it's pretty nasty stuff if it gets into your eyes. That pint will go a long way, but you have to remember not to paint out of the can as you would if you were painting your house. Open it, use a ladel to take out what you want to use and reseal it asap. Then store it in the fridge when you're done at the end of the day. And there's one other thing I've learned about storing it in the fridge; it never returns to the consistency that it was before it was put in the fridge. In other words, it will be noticeably thicker, even after it has had time to warm back up to room temperature. No problem, you just have to thin it with Por solvent to get it back to as thin as it was when you first opened the can.

POR-15 does not stick well to old paint so remove all old paint that you can first. If you can't get all the paint off that is ok but, try to have as little as possible left.

How long does it take that stuff to dry?

About 1 to 2 hours, depending on humidity and temperature, to get to the point you can put on a 2nd coat. About a full day to cure to "dry" and about a week to cure completely.

The best way to apply it is not by brush! The best way it to use those foam mini rollers from the big hardware stores like Home Depot! Now, there will be thousands of mini bubbles at first so don't panic. When the paint starts to "tack", they will roll out.

The rollers don't drip and they dont leave brush strokes or loose hairs. If you get POR-15 on you and you don't get it off before it dries, you will wear it for about 2 weeks. It does not come off skin when dry!

Mike, heads up!!! I talked to the regional distributor for Por products in this area and he said it is best to wait at least eight hours before applying a second coat. If it's done any sooner it can cause the first coat to lift.

I don't know that I agree with that regional guy, Randy. The instructions say to wait until it's dry to the touch but still has some drag. In my case that was about three hours on a warm day with just a little humidity. I put on the second coat with no problems at all.

It's ok to wait longer, you just might have to sand it with 600 grit before applying the second coat.

The stuff cures faster on more humid days. I'm not sure yet whether temperature makes that big a difference as long as it's not "too cold" or "too hot" (whatever those are).

thanks for your help guys... i'm going to start doing it on wednesday or thursday... if there is anything else i need to know, pass it my way. also, is it okay to pain thte rusty exaust pipes, or will it get too hot?

I've not had any problems by waiting overnight. The point he was making was that it's better to wait a little longer to apply a second coat rather than apply it too soon. You will have big problems if you recoat too soon. Ask me how I know.

I'll have to give the foam roller a try. I tried spraying it, but I really didn't like the way it turned out. Plus, you have a lot more waste when you spray, not to mention the need for the respirator. My brush painted fenderwells look like glass. But I will give the foam roller a try on my floor pans, because I always like to experiment.

Huck, I just noticed your next question and the answer is, use their high temp finish. They have it in cast iron gray, aluminum silver, and black. Check out the Por site at http://www.por15.com/
