Best is sand blasting and powder coating.

A 2 pack paint would be ok and reasonably durable.

I've previously hand sanded one and painted with pressure pack "Kill rust", lasted a few years before it needed doing again.

Agree with the sand blast, but not the 2pack. It is to hard and will chip instead of scratching. Power coating would be the best but at a price.....

Or as Terry said, pressure pack Kill rust.......

Cheers

Hi Paul,

I did mine about 3 years ago. It was originally powder coated black.
I have not found powder coating to be durable in a wet environment. Moisture seems to get under the coating then it rusts and flakes off. Furthermore, it cannot be easily touched-up if damaged.

Had the bar sand blasted then applied two coats of White Knight Cold Gal with a brush.
Followed that with two brushed coats of White Knight Rust Guard hammered finish in Charcoal colour.

The hammered finish disguised the areas of rust pitting and imparted a good looking finish overall.
It was a great success despite being subjected to a salty environment on Fraser Island several times. The finish is tough too..... has pushed through quite a bit of scrub without damage.

Similar products could be used if White Knight not available in your area.
Cheers
Allan

I colour-coded my new ARB deluxe steel bar.
1. First a rub-down with a pot scourer to lightly roughen the smooth powder coat surface.
2. Spray a coat of single pack etch primer.
3. Spray 2 pack base colour. Metallic silver to match vehicle for me..
4. Spray finish with 2 coats of 2 pack clear.
I used DeBeers products - top quality.
After 3 years it still looks as-new.

Thanks for the replys, but I'm sure not going to spring for powder coating.
Home spray job by yours truly!

I'll back Allan's recommendation of White Knight Rustguard. It's a highly durable epoxy paint.
Painted a mates Komatsu forklift with it in 2007, and it still looks great.
Just make sure you do the proper amount of preparation and use the Rust Guard primer.
A paint job is only as good as the prep.
The previous mention of powder-coat coming off, is due to lack of prep work on the bare steel.

Cheers, Ron.

I've been a fan of the White Knight epoxy for many years. But these days I use the Dulux epoxy which is considerably cheaper at $10 a spray can and equally as good. Both available at Bunnings.

.
As I said above, I applied both my primer and my finish by brush rather than aerosol spray.
I do not know if the paint formulation differs between brush and spray but I believe that the paint applied by brush delivers a more durable finish. Possibly due to producing a thicker coating than an aerosol sprayed finish. Certainly, in the case of a job such as the bull bar, brushing is more likely to yield a better build in internal corners, a place where rusting often occurs.
My use of hammer finish paint eliminated any possible blemish of brush strokes on the cured surface.
Brushing paint is also a lot less expensive than aerosol.
Cheers
Allan

Gday Allan,
You may use a brush but the original poster wants a spray can.
In years gone by, I would agree 100% with what you said.
But I use the spray can because in my hands it is a great finish and the costs are different.
A 300gm spray can of the Dulux satin black epoxy costs $9.95 while a 250ml can of white knight satin black epoxy costs $17.90. Sure you lose some spray in the air, but depends on what you are painting. I painted a 4wd storage system and cargo barrier today with a single can.
Didn't know you could brush paint the hammer finish, so I've learnt something new!
BTW the Dulux hammered finish is $12.90 a spray can!
Cheers
Phil

The cost of spray paint reflects the amount of 'solids' included in the mix. The more solids, the better the paint quality. UV penetration, color stabilityu, water ingress etc. If you are into saving money then there's always the SuperCheap $3 cans.

Do a Google search on aerosol paint solids. I'd be using the White Knight or Wattle.

Malcom,
Nobody is talking about $3 cans.
I did your search and came up with nothing specific about the Dulux or White Knight epoxy paints.
Can you point to your evidence to say that the Dulux Metalshield is crap epoxy paint?
Bunnings no longer stock Wattyl's Killrust and replaced it on the shelves with the Dulux Metalshield epoxy.

Huh?

What part of "Do a Google search on aerosol paint solids" is giving you problems.

Where did I say " Dulux Metalshield is crap epoxy paint"

Couldn't care less what Bunning sell.

Mate, have a coffee and read the post again.

Good tip, I may go brush if I use a hammered finish.

If you want durability and are not overly concerned about fancy finishes, sand blast and hot dip galvanize. It will far outlast whatever it's bolted to.
