Attention: TDR Forum Junkies The best Rustoleum for undercarriage use
Having worked for Rustoleum's Industrial Div. for a number of years, I have had the opportunity to be involved in lots of OEM and Refurb projects on trucks, trailers, campers, street rods and heavy equipment. In nearly all cases, the product of choice to coat new or rusted steel on undercarriages is the Rusto DTM (Direct To Metal) Epoxy Mastic. It is also known as the 9100 System. It is one coat and no primer is required. Because this system has a rust-stop built in, all that is needed is on a rusted surface (just about everything on a Dodge truck undercarriage) is a light wire brushing. It is a minimum prep. system and you don't need to go through hoops in cleaning whatever you are coating. For oil removal, a quick wash with a brush and dishwashing detr. , rinse and let dry, does it.
9100 System is an industrial epoxy and it is made up of two parts. That said, it is designed with a 1:1 ratio. One part of the base is mixed with one part of the activator. Both parts only come in gallons, but if you wanted to do a transmission, just mix 1/2 cup of part A (base) with 1/2 cup of part B (Actv. ) and you have a cup of super coating. This product sticks to mill scale, rust, aluminum, SS, concrete, brick and every known type of clothing. One coat is all you will need for the life of the truck. It is designed to be sprayed out of a gun right after mixing. If you want to brush it on, let it sit after mixing for 30 minutes before use. Even brushed on it levels very well with little or no brush marks. On a transmission or most any other parts of the undercarriage, you don't need a spray look anyways. Everything from my tractor to my horse trailer has 9100 on it and it never wears off or peels. You can get it at Loews or Home Depot or Grainger (more bucks though!)
It is good for up to 300 deg F.

I know its not for everyone, but when only the best will do, this is it.
