POR 15 equivalents?

If things are reasonably clean, I've have had good success with flat black Rust-Oleum, professional (the larger can, silver, not white).

It holds up remarkably well for what it is. Quick and tough.

I did the underside rear wheel tubs on the 76 with that, that has been 8 years, with about 6 being a daily driver in any and all weather conditions and they still look like when I sprayed them. Just DA sanded, no primer, didn't really wipe them down.

And this is with a spray can or brush on?
That looks really good, actually.

Here's a couple of pictures of those wheel tubs, think it was semi gloss, not flat. Still have held up way, way better than it has any right to.

Dirty obviously, but that's because I never really wash the truck.

That’s held up real nice especially for where it’s at. Those wheel tubs get abused pretty good

How is the rust situation where you're at?

I'm a fan of epoxy paints for most chassis applications, its affordable, has good adhesion and is fairly chemical resistant.

Another option for the air catalyzed "Rust inhibitor" paints is Rust Bullet.

Paint peals and surface rust happens pretty fast but nothing serious. It’s very wet in western Washington.

And this is with a spray can or brush on?

I'm a spray bomber.

Or a spray gun.

Brushes and rollers reminds me too much of house painting

Both examples I shared were done with spray cans.

In the past I have used POR15 but was not super happy. This was back in the late 80s when the first started and it peeled. Since that time they have added cleaner, prep and other products to their lineup. Back then they only had the black rust coating.

A few years ago I started to repair a Caterpillar backhoe with a pretty rotted cabin. What I did not cut out and replace I used a product called "Mastercoat" to paint. I hit the rust with a wire wheel or flap discs. I cleaned it good and painted the Mastercoat on. The product is silver and is UV stable. I topcoated it with Cat yellow enamel.

Mastercoat has frame black and stuff. They sell mainly to car restorers. I believe the product is made for painting bridges.

So far going on 5 years outside in the weather and it still looks good and no rust came back.

Yeah, I’ve heard the down side to POR 15 is you really have to make sure it’s CLEAN. They’ve got so many products for cleaning that it gets expensive to do it “the right way”.

This Mastercoat looks to be some tough stuff!

Another possible choice is John Deere Blitz black, I have not used it personally, but have heard good things about it durability wise. They also have a 'medium' black, more of a semi gloss I believe. Available at your local John Deere dealer. Can add hardener to it as well.
