Rustoleum 2 types?

sald · Jul 31, 2019

I painted my Farmall A with HVLP using Rustoleum "Farm Equipment" paint. I got it from Amazon and today picked up what I thought was the same thing at Tractor Supply. I just noticed that it is "Farm and Implement" both are International Red.
So what is the difference?

Stephen Newell · Jul 31, 2019

Can't tell you the difference. I know I painted a Kubota tractor about 10 years ago with farm and implement paint and it's holding up pretty good. It hasn't faded very much at all.

I sent Rustoleum a message. The description on both products mentions a brush and nothing that distinguishes one from the other.

It may be the paints are the same except for the amount of thinner. The farm and implement paint was thin enough I could spray it without thinning it. You just have to wait to hear from them. Since it's formulated for implements too, it might have some urethane resins in it. They should put this kind of info on the cans instead of warning labels in multiple languages.

If you add the gloss hardener (which I recommend highly) you need to mix in a little enamel reducer for the hardener to work correctly. On your deal chances are they slightly changed the label, so you got one with the old, and one with the new label.

So they said that the implement paint was more durable and fade resistant. Also, you can paint over the equipment paint with the implement paint after 48 hours.

The hardener will still makes it last much longer than it does out of the can. Another plus with the hardener is that you can sand, and buff out any runs, or dull spots. Without the hardener you can't, you will have to respray it.

That would mean the implement paint has stronger solvents in it and would dry faster. Even after 48 hours if you sand the paint with too coarse paper the solvents can get under the equipment paint and lift it. If you roughen the surface just use a scotchbrite pad or like 400 grit paper to keep that from happening.

Good info. Thanks.

I have been mixing with the following:
5 parts paint
2 parts acetone
10cc valspar hardner

Any thoughts? It is fine but maybe it can be improved?

sald · Aug 3, 2019

Sorry meant ounces...
5 oz. Paint
2 oz Acetone
10cc hardner

I double as needed because I have been painting parts as I remove them

Acetone is too harsh. It might damage the resins that make it up. I went and got a can of the implement paint and the label instructions say to use mineral spirits. Spraying it though you could use naphtha. I wouldn't use anything stronger.

sald · Aug 3, 2019

I read that as well. I saw internet articles that said mineral spirits or thinner took longer to dry so I went with the acetone. I will look into naphtha.

Stephen Newell · Aug 3, 2019

Mineral spirits does make the paint dry slower. They recommend that for people that apply the paint with a brush. Naphtha is a suitable solvent that dries faster is why it's recommended for spraying the paint.

Actually the regular Rustoleum in a can, used to recommend to thin with acetone if spraying....

electro · Aug 4, 2019

Just go to the Rustoleum site and see what they recommend for thinners. The TDS sheets I found recommend acetone. Both appear to be plain old oil modified alkyd enamel, nothing special, and do not appear to be acrylic or urethane modified.

If you use a hardner you may want to use a ratio like 8:1:1.

When in doubt, just go to the manufacture's TDS sheets. They will be more acurate than any comments on YT.

I use acrylic enamel reducer, they have slow, medium, and fast drying reducer for varying temperatures (slow for hotter temps, fast for colder temp). They usually have the temps on the can so you can get the right one.

Keep in mind that this project is a recoat. You might get away with using acetone in the farm and implement paint to thin with if it was all fresh but putting it over the farm equipment paint is very risky. It could easily lift. I don't think having the paint dry a little faster is worth the problems it might cause. Thinning with naphtha won't hurt anything.

sald · Aug 6, 2019

I have stripped it to the metal so far and primed. The back end I will not do that, so Naptha it will be.

sald · Aug 6, 2019

That is where I got the Acetone thinner recommendation from. And as stated here, it was on the can.

Stephen Newell · Aug 6, 2019

I couldn't believe it but it was true Rustoleum said you could use acetone in the paint. I don't like the idea. I've tried to put rattle can paint on enamel before that was months old and had the paint lift.

Since you are down to bare metal just be sure to put all the coats on that you need within the recoat window. If for some reason you have to go back over it later it would be safer to thin with naphtha after you exceed the window.
