    Who has done their undercarriage in POR 15?
    How much did you use?
    Where did you get it?
    What did you to the metal to prep it?
    Does it make mud easier to get off?
    Was it worth the trouble and money?
    Any other tips?

    I have done it... used a roller and coated the wheel wells, tailpan, some of the frame, etc. Boss has also done it and has some pics up in the BBS boards. I like it... I used about 1 Qt. I did use the metal prep because it helps etch the surface supposably, but leaves a zinc coating which helps fight the rust and moisture. I also coated the inside of the rear of the truck w/ it. Great stuff... gets nice and hard... lasts a long time... a hundred times better then that cheapie undercoating in a aerosal can and much cheapper than Rhino-lining etc. I can't say it helps w/ the mud coming off but definetly keeps the water out [​IMG]

    I'll try to answer these as best as I can
    How much did you use? Kinda hard to tell I bought a gallon did a bunch of projects and still have at least a quart left...I would say about 1/2 gal to do the entire underside with a brush

    Where did you get it? Bought my first sample quart from 4WDhardware...Got 2 gallons direct from POR15 website

    What did you to the metal to prep it? Follow the directions pretty much. Scuff down smooth surfaces, chip/scrape loose rust etc. I sandblast as much as I can so I can see any cracks or thinspots to fix

    Does it make mud easier to get off? Mud sticks to it as much as any other painted surface.

    Was it worth the trouble and money? I swear by the stuff. I have had powdercoating fail after 2 winters and the POR15 is still as good as the day I applied it...I tried to grind some off when I changed spring perches took much more effort than paint. IT IS TOUGH STUFF!!! The only downfall I have had was haping to topcoat it for UV resistance (not necessary for under) It wont fail or weaken but looks like crap when it gets damaged.
