Tractor Paint vs POR15

I hope this is in the right section, I don't want Chris to give me an internet whipping.
I need to paint my axle, there is no rust and I do not see the point of buying the much more expensive POR15 opposed to Tractor Paint (TP). Tractor paint, although it takes 9 years to dry, it a solid trade off and cheaper. For my application I do not see the need.

I'm not going to put my non-scientific internet research into the fold. I don't know crap about paint or paint application, so I'm not going to act like it. If I had rust, I see the point (Paint over Rust, duh), but bare, shiny clean metal does not appear to fit the application.

So school me...

In your case, POR-15 is not the right paint.
Tractor paint is good, but Rustoleum will do the axle as well.
Eastwood is appropriate inside the frame, if you want to keep your rig forever.

If it just a price thing, is $22 for a application specific solution really that much more than tractor paint?


I used this stuff on a old trailer frame and it sticks. Really well. Prep work is key though.

POR is for use over slightly oxidized metal, it has acids in it that convert the oxidization to another metal compound and then it gets sealed by the paint to keep it from rusting further.

I would think it does have phosphoric acid. I have some at home I'll try to confirm. I'm in this process of touching up the Jeep frame and my truck frame with the Por 15 and then I'm going to get the Eastwood in frame stuff and then I'm going to try some sort of wax I saw suggested. The wax I'm going to try to do on a regular basis. I probably need to grab one of the bore scopes too. First things first is get ahold of a pressure washer and really really clean this thing.

Btw I can't blame the previous owner on rust or anything like that. There was a little bit of surface rust but it all went down hill with me and all of our mud/sand mixtures.

I use tractor paint a lot for projects like that. Get some hardener...generally right on the shelf next to the paint. It dries much more quickly with the hardener in it.

I've used POR as well and its impressive stuff, IF you can follow the directions to the letter. If not, it won't stick...it will start peeling in a year or so.

I know this thread is tractor paint vs por15 however something I started using last summer and no rust has come back yet (through a salty Iowa winter) is Master Series. I've heard it is kind of similar to POR15. It has a high aluminum content to help fill in pitting. It is hardened through moisture and doesn't dry well when it gets too cold. I sandblasted or grinded off rust, then applied phosphoric acid, then two coats of Master Series and then a top coat. No rust has come back yet fingers crossed. Another option to look into.

One is never free from rust no matter what product you use. A regular maintenance schedule, along with proper prep. and product are required to keep rust at bay. My own schedule includes a routine inspection of all rust prone areas as well as removing any rust that creeps in and touch up. I'm firmly convinced there is no 'one and done' miracle treatment or process.

POR-15 is not the right paint.
My thoughts as well, I went with implement paint.
I may be getting to that point, I've come across some flakes inside the frame. Outside is perfect, inside has some flake.
price thing
Not really a price point, more of ease of use. I don't see a point to brushing on paint when I can get away with a rattle can. I had not heard of this brand, thank you for the link.
slightly oxidized metal
I'm assuming that means, no rust = will not adhere as intended.
Get some hardener
I didn't even think of that, I have one coat of tractor paint on, I'll have to pick up some hardener this evening. Are you using the brush on? I am using the rattle can, easier/quicker to apply.
IF you can follow the directions to the letter
I looked at the 3 stage kit way too many steps for me. I can see if I was attacking a rusty frame.
Master Series
Thank you for the idea, too many steps for my current project though. I will look into it for future reference although it looks like it was the go-to product prior to POR came out.
Does anyone use tractor paint over Por 15
I've only used it to repaint motorcycle parts and now my axle. It's thick and holds up well but I've never had anything long enough (5+ years) to see any long term results. I am not looking for show quality, more just to cover bare metal from the elements. We shall see how well it holds up under the Jeep.

I truly believe the end result no matter which product used will be the prep work, I'm glad my axle was not rusted to crap and was fairly easy to clean up.

Well I was thinking of cleaning up the frame of mud/grease/surface rust/etc. Using the Por 15 and then the Massey Ferguson Gray tractor paint to top it off. Then Eastwood inside the frame and then wax. I used some rattle can to touch up spots less than a year ago and that seems to have been a waste.

What holds up to brake fluid? Just thinking of touching up the booster.

Kinda. I buy it by the quart, mix it with thinner and reducer, and spray it from my Harbor Freight gun. I did my rock sliders that way. They turned out great and have been very durable.
