How do you paint a custom built, steel front bumper (flat black) for a jeep ? Any suggestions?

I recommend using POR-15. They make a fantastic product that is essentially a super-resilient primer for metal. If you use POR-15, follow their procedure, which includes cleaning, applying a phosphate, applying POR-15, and applying a topcoat. The procedure below works with POR-15 as the primer, or for the primers described.
Here is a detailed write-up (paraphrased) from a paint guy on a Jeep forum. Complete the following steps in a WELL-ventilated area. Note safety and handling precautions - some of these can be nasty chemicals if mishandled.
Step 1: Clean with a degreaser such as mineral spirits or xylene or acetone, all available from a hardware store.
Step 2: Sand with fine sandpaper (325-400 grit) This roughens the surface for better paint adhesion.
Step 3: Apply rust conversion/phosphating (look at a hardware store for rust converter, rust neutralizer, rust dissolver, naval jelly...) This dissolves any residual surface rust and applies a phosphate layer to the surface to help the paint stick. Apply the chemical, scrub any rusted areas (if you have any - probably not with a newly made part), hose off, and dry thoroughally.
From this point forward, handle only with gloves on and do not wait more than 1 day before applying the first coat of primer.
Step 4: Apply primer. Choose one of the following as a primer:
• Alkyd - Oil based primer for steel. Tendency to chip until it has time to fully cure, excellent corrosion resistance.
• Epoxy - 2 part paint (mix part A and B together like the glue). This is top-of-the-line, what the auto manufacturers use, but it's hard to use - once mixed, it is GOING to dry HARD.
• Rattle can - easy to apply, will require reapplication much sooner than other choices.
Don't use a water-based primer. You will get very poor results. Don't worry about UV resistance in a primer, that's what the topcoat is for.
Apply 2 coats of primer, and sand with fine sandpaper (325-400 grit) between applications.
Step 5: Apply topcoat. This is mostly for appearance and to stop UV from damaging the primer. Recommendations:
• Alkyd topcoat – Good UV resistance, good to very good scratch/mar resistance, good corrosion resistance. Very good adhesion to the paint below.
• Acrylic urethane – Also known as auto topcoat. Excellent UV resistance, very good to excellent scratch/mar resistance, 2 part paint like an epoxy (disadvantage and advantage), very good to excellent adhesion to the paint below.Source(s): POR-15: http://www.POR15.com The procedure above is from a write-up on Rubicon Owners Forum. http://www.rubiconownersforum.com/phpbb2/viewtopic...

I used Rustoleum. My bumper came in bare metal from the builder - sand it so its smooth, put on a few coats of primer and bust out the rattle can. You may want to look into having it powder coated - tuff as nails and not too expensive - maybe $75.

Mask off the vehicle or remove the bumper. Prime it first, then spray it. Use PPG flat black and a good spray gun.

Not going to bring my political views into this, but some (other) girls have claimed to find Mr. Ryan physically attractive. So that's something to take into account if you're going for frightening. Unless drooling fangirls are sufficiently frightening for your purposes...

ok why paint it when you can bedliner it! yep give it that rough flat textured look and let it take a good beating.
yep buy some roll on bedliner.
