painting a bare steel bumper

my shiny new bumper from jcr offroad just showed up! but the one thing i forgot about was that they ship them unpainted.

i know absolutely nothing about painting metal of any kind. so what do i do?

i just want the most durable black paint job possible. i don't want it to scratch off and start rusting the first time i hit a rock or something.

can i use bedliner on it? is there any good reason not to?

I'd hit it with a few coats of good quality primer then use a good paint on bedliner. That stuff is pretty tough.

Sand it first.Acid etch primer(they actually sell it in a spray can).It'll give you some bite.I always use auto paint but that's kind of an overkill for a bumper.I'm sure some other guys have used some tough paint you can get cheaper.

Clean and prep the metal like posted above. I had some POR15 I used as a base coat and then used Duplicolor auto paint from Advance Auto. I sprayed it black and the Duplicolor paint goes on real nice. Very hard to mess it up. If it does get scratched or chipped $5 at Advance and I just touch it up.

I have yet to see powder coating hold up. There maybe some people that can do it right but I've never seen it. Everything I've run into has sheets of powder coat peeling off rusty metal. I spent maybe $40 on paint and prep materials for my bumper. I don't think a properly done powder coat job would be that cheap...

Since no one else has mentioned it. Go buy a big can of acetone, some rags, and some chemical resistant gloves. Once you get done sanding the bumper lightly, clean the crap out of it with the acetone. Put on the cloves (cause its rough on hands) and pour some on the rag and wipe it all down several times untill you can wipe it with a clean rang and you get no crud on it. Also, make sure you do this OUTSIDE. The fumes are kinda rough. But makeing sure the metal is super clean like this before you paint will make all the diffrence. The metal has to be clean of all crud, oil, dirt, etc.... Otherwise the paint wont stick very good and will flake off easy, it if even sticks at all.

I highly recommend Rustoleum Professional. It's tough, dries quick, and comes in flat or gloss.

My front bumper has taken a beating and it only has one or two scratches that I'm too lazy to get out there and touch up. Rocker guards, rear bumper and wheels look like I painted them yesterday...

I used Duplicolor spray on bedliner directly on the bare metal of the bumper. I prepped the bare metal well but wish I had used a primer coat. The bedliner peels pretty easy when it gets bumped and I can see a few small rust spots. It is easy to patch because I just carry a can of duplicolor spray with me, but if I had to do it all over again I would have used a primer coat first.

so, with self-etching primer there is no need to sand?

and what's the best way to support the thing while painting... like, to set it somewhere where i can paint all of it at once. or is that too much to ask for? thanks for all the help so far.

I don't know the answer to the primer, but i have a hook in the ceiling in my garage. I hang everything I paint buy a nylon strap that has hooks on each end. That works pretty nice.

I use plasticote bedliner spray. It's not that hard to scratch, but easy to fix. It has to go on bare medal or original paint. Every other paint I've tried to put it over bubbles up

The first thing you do is CLEAN it, get all the oil and metal protective coating off it. If you sand it 1st you will drive that stuff into the metal and it is a pain to clean later. And the paint will never stick. But after cleaning just prime with a good bare metal primer and cover it with either bed liner or a good enamel paint.
