I get mine as clean as i can,tape off all i dont want black and shoot a thin coat of spray paint. It has worked great for me. Im sure its not the best way, and only lasts about a year, but its really easy and cheap.

i found a rubberized coating stuff in a spray can.... but then that would leave everything underneath with a texture... im not sure if I would like that.... but i know it would be more durable than say just paint.

That rubberized coating is soft and will grab and hold lots of dirt and particles in it a smooth finish would look better longer

POR-15 or Chassis Saver.

there was an article in one of the latest diesel power mags that had a whole write up on that. they took a obs 7.3 and used stuff to kill all the rust then coated everything with the black stuff that will last forever it was very interesting to read but seemed like a good deal of work

I use rustoleum industrial flat black, touchup every 1-2 yrs but usually does not need much touchup

I have used this on all of my trucks so far:
VHT SP671 - VHT Epoxy Paints
If you can get a coat on before the rust gets out of control, then touching up every spring is pretty easy. When I trade my '05 in on my '07 the undercarriage was nicer on my trade than on my new truck!

I used a metal prep rust coverter called Picklex. This stuff ate the rust & left a nice coating over the metal to seal out moisture. Picklex-20 Click Here for Options: Autobody Store

Then I put 4 coats of Zero Rust on my frame. It doesn't get hard & peel off like POR does & leaves your truck with a great looking finish.

i wouldnt use any rubberized materials. the actually will hold moisture in. use something made for the job. POR 15
