What is good to use one the underside of the car? Mostly for rust prevention. Also What can be used on the exhaust? Is Por15 the best? That is what it seemed when I looked around.

POR 15 is good for frame. On the exhaust? Not much. Grill paint works.

I never found anything to stay on Fiero exhaust manifolds. I even tried the special paint used on jet engines w/ afterburners and it was peeling in a few weeks.

I'm currently planning to use this Black Satin ceramic paint.

http://www.techlinecoatings.com/Exhaust.htm

It is supposed to withstand up to 2000*F. Anybody used this?

I've used Por 15 in the past and Eastwood Chassis black more recently. Of the two I have to say that I think the Eastwood stuff is more durable. The Por 15 would scratch off pretty easily.

What do auto manufacturers use? All my Honda's came with factory rustproofing underneath, and it lasted 20 years. Are they just using POR15?

No, they are using a sound deadening material... an "undercoating" if you will. This is not what POR-15 is. POR is a paint (in simple terms).

POR 15 is a rust converter/inhibitor; it's not a paint. It's not made to be a finish material, & in fact does not hold up well to UV or weather. If you want a smooth finish that lasts, do the proper prep & use epoxy primer & urethane paint or industrial enamel with a hardner. Seal all the seams after priming to keep out moisture. If you want even more protection, use a good rubberized undercoating (not the spray can crap) over the paint.

I found that the duplicolor metalic paints that you have to apply a base coat then the clear color top coat work really well in high heat applications and I used it on a rx7 drift car and I know that brakes get really hot so it was a shot in the dark but over 2 years later its still good. The ceramic stuff will work but if it gets any oil on it it will crap out because my old icon duke in my monza got a fresh paint when I rebuilt it and I used the 1200 ceramic paint and it is chipping where the oil comes out from a bad valve cover seal. But if your painting pieces that get really hot I use black oven paint and that seams to hold up to anything and is good against rust.

Anyone have any experience with DEI paint? I saw it in another thread and summit sells it. It is about a 3rd of the price of por15, so I'm thinking of giving it a shot.

An important point. POR 15 works much better on rusted surfaces because it bonds to, or reacts with, the rust. Putting it on a good painted surface (or on clean steel) isn't very effective, because it won't adhere or harden properly.

If you can find it, one alternative is "Hammerite", which is a specialised anti-corrosion paint for metal surfaces (I haven't used Rustoleum, but it may be similar). As with all painting, the secret is preparing the surfaces well: stripping, sanding, or priming - depending on what the final coat is to be.

For the chassis underneath the car, after getting rid of (or converting and sealing over) the rust, the next step in protecting it is to spray Waxoyl or Dinitrol on to exposed surfaces and into box sections - messy stuff, but it keeps the moisture and rust at bay.
