    Does anyone have any recommendations for painting the undercarriage? I was going to paint it with duplicolor rubber coating so I can stop the rust cancer before it sets in and make subsequent cleanings of it easier.

    I used duplicolor bedliner and it's already rusting through again. I've heard good things about rustoleum

    I have heard good things about POR15 even though I haven't tried it myself yet. I am considering it.

    Ok so I'm going to go with the duplicolor rubber paint, since on that thread someone said the rubber lasted several years. I'm also going to use high temp paint on the calipers and rotors.

    Going to do this when I get my new rear diff cover and before I lift her so I don't have to worry about getting paint on the shiny new shocks!

    if you are removing all of the rust before you paint i would recommend chasis black coat made by por-15 it is similar to por-15 but is meant for application to bare metal, or as a uv resistant top coat to por-15 aside from that the durability is equal to that of por-15, then i would top the cbc with evercoat undercoating

    The "frame rails" have holes that will fill up with whatever you run through. If I was serious,think cleaning rails out and using an oil type coating would make sense. I know mine were FULL of fine sand/dirt/crap.

    I use the rustoleum enamel that they have at fastenal. works really well, front suspension is getting it this summer. Did my steel rims with it for my fusion and it holds up great. Did some bare steel pliers that were a little rusted, looks like powdercoat. The semi gloss looks flat which is nice.

    Tried cans of tremclad, rustcheck black, Catipillar black enamel, asphalt undercoating and rust coverter and the above works best.

    Haven't tried hammered but hear good things.

    I've tried it hammered but overspray became a problem.

    Well I sprayed a little bit of the duplicolor rubberized undercoating at work on a shelf. It looks like :poop: brown. So I'm going to use the rustoleum instead since you guys seem to love it so much

    well i had my liberty undercoated by ziebart and then i went and got some eastwood internal frame coating and coated the inside of the frame rails and works great to coat the inside of the body panels. I used about three bottles it is the best stuff to use and does not take long to coat frame rails with this.

    I live in chicago so salt is my culprit first i clean the under side with a power washer no bed liner or rusto will help any if any contaminants are being sealed in with it then i got at it with a can of gloss rusto and a quart of rusto to hit all the tight spot then i high heat rusto anything that gets hot i usually do this once a year it can be quit relaxing under the libby with a paint brush

    I've started using fluid film on the undersides of my Jeeps. It doesn't cover the rust, just keeps it from spreading. You cant just spray paint or undercoating over rust, the rust will continue to rust.

    Ive bought the fluid film kit, comes with a spray gun, bottles, extension tubes for doing the frame, etc. Works good. I use about a gallon of fluid film a year on my Jeeps. About $40 or so.

    The unibody support rails running along the bottom of the body, hence the quotations around "frame rails"
