I've designed my perfect 4 way shepherds hook , to hang bird feeders on.
I think I have found a welder to cut the 20 ft. rebar up and put it together.

now,
whats it going to take to coat it with stuff and make it look nice out in the yard.

rusty brown ain't gonna cut it.
I don't know for sure , but I don't think that powder coating it is in by budget

plastidip ?

Paint it with Rustoleum? It comes in many colors. We are currently having our house repainted, the chimney cap is being done in blue Rustoleum.

If you notice highway construction, bridges etc..., They use coated rebar (green colored)). I have never tried to buy it so I don't know where it is sold.
I would give the rebar a wire brush and spray it with Rustolleum.

Squirrel repellent paint?

That’s epoxy coated. It’s not readily available in small quantities in most places.

I’d go with rtquig’s suggestion for cleaning after welding, but don’t grind it shiny smooth or it be harder for the primer to stick to the metal. If you get it too smooth, scuff it up with a coarse sandpaper or emory cloth. Use a primer to get good bond to the metal and then give it two coats of paint, taking extra care at the connections. Some paints have primer included; if you use one of those, again be sure to coat the joints well.

You could paint it first with a rust neutralizer. There used to be a product called Neutra-Rust, but I'm not sure if that is still made. I'm sure there are such products you can buy, though.

I would double check the powder coat price. I think we had an old gumball machine parts blasted and coated for under $50.

If you can’t etch the re bar, epoxy primer will give you excellent adhesion and good corrosion resistance then you can go to your color. If you wish, shoot two or three coats of clear over your color. Of course using clear will give you shine and some uv protection.

A body shop might do it at a reasonable price.

Is that a phosphoric acid product?

I think the Ospho brand of liquid phosphoric acid rust treatment is still available, and there's also the always popular naval jelly, although I think with naval jelly you have to clean it off before you paint.

I'm not sure what was in Neutra-rust. This product looks similar in that it converts rust into a black compound that can be painted. It's tannic acid and a polymer.

The linked product sounds like a friendlier version of Ospho, which converts iron oxide to iron phosphate. (Naval jelly is chemically the same thing, just in a gel carrier so you can really slather it on rather than an evaporating liquid carrier you don't have to clean up.)

POR15 is good. It will lose its sheen quickly but if used as a base with a top coat of your choice it should serve well. Powdercoat would be my first option.

If you’re going to spend the money to have someone cut and weld it up for you, I’d spend a little more and get it powdercoated. Check with local shops, it may not be as much as you think for a small part like that.

If you lived in Northern Utah, I'd powdercoat it for you no charge.

Ospho or similar product will convert the rust to a different oxide, and then spray it with rustoleom or krylon.

That's a great idea. A few years ago, my mom tried to find replacements for some rusted central air vent covers that were a nonstandard size. She couldn't find exact replacements and eventually got a little local shop to sandblast them and powder coat them for a surprisingly reasonable amount of money.

On the DIY side, I think good epoxy paint is about the most durable outdoor coating that is reasonably easy to apply at home.

OSPHO is a rust neutralizer and the best I know. Brush that on, let dry, prime it and then paint it with rustoleum.

Is Naval Jelly not in use anymore? I still have some and a couple of months ago used it on a car part that a battery leaked acid on.
