JD 3 bottom plow restoration

Wildride47 · Oct 10, 2015

I'm taking our plow apart to have the entire thing media blasted to remove the paint and rust. I'd like to hear some thoughts about what paint coating would be recommended. My last restoration was an old Camaro and I shot a self etching primer and PPG paint. That was a much different application than than the punishment a plow is put through. I need some expert advice

Thank you, Greg

If you liked PPG, use it. It's as durable or more durable as any. Cheaper paint will fade. If sand blasted don't use etch, use epoxy. Sand blasting makes etching redundant.

Is there any product that's giving better results than another? I know everyone has a preference, just wondering what others are having success with.

Just as CNKS said below. Anything with a blast profile, I would apply two coats on PPG Omni 170 epoxy primer leaving 15 min flash time between coats. Two coats just fills the profile and seals it over better than one. then single stage urethane it within the recoat window and you will have a bullet proof job. It can only work where it is applied so you are doing it right to disassemble the parts first. Some don't and then badmouth the product.

When you use quality paint, meaning PPG, DuPont, Sherwin WIlliams, BASF, etc, it is matter of opinion, depending on the individual. All the major paints have more than one paint. Omni is the cheapest PPG, but the cheapest one is much better than the ones sold by farm stores. On a plow or a tractor, Omni urethane is better than Omni acrylic enamel, but urethane costs somewhat more. On a car, PPG Concept should be considered. Again, which of the name brands to use is a matter of opinion. I use PPG Omni single stage or base/clear depending on what I am painting, I'm not going to say it is better or worse than DuPont, etc

I can't agree more, disassemble, clean and paint the components. Let it cure properly and then reassemble. I could never understand putting the effort into painting if you don't do the prep correctly.

What really keeps my old machinery in good condition is after cleaning / priming / painting, I keep it covered out of the weather. Simple to say, and I don't have nice machinery sheds yet for everything, but for now I use heavy black tarps with weights. Sometiomes I lay on old galvanized roofing panels. I cover the tires, etc. too, and after sitting for years, when I undover things, they're in good condition. Just my opinion, but WHATEVER you do outside of hot dip galvanizing will not survive years outside of weather. The only caveat is don't trap moisture and don't build nice homes for miceys.

No more paint than you are going to use on a plow, get the 2 component urethane (one of the top 4 brands) and turn your gun down so as to not waste a lot on overspray that flys on by the plow parts. A quart of JD green will easily do a plow.

Because I live in an area where there are no farm stores I only know auto body supply brands of paint. Since these paints are automotive they stand to the weather. All the paint problems on here seem to be from cheap paint.Brands I have heard of BASF , Glassurit, Matrix < Dupont . Ditzler{PPG}. And high priced custom House of Color paint owned by Valspar. If it is made for an auto finish it will hold up well on a tractor.

I used PPG's Omni on the Troy Bilt tiller in 2006 still looks good and I used Dupont's acrylic enamel and the blue was from a local tractor dealer.
The blue was acrylic enamel too. Hal

I would use epoxy primer. Unlike other primers, it's waterproof. It's like a hard plastic shell. When the paint gets scratched (it's a
plow, so that's a given) - the epoxy primer is there as another layer of protection.

Nothing's going to save you from heavy dings from big rocks - but the epoxy primer will keep things safe from all the smaller stuff.

I'm very happy with the results on every implement I've used it on. I use ppg, but I'm sure other brands are similar.

Would you prime and assemble before color coat or prime and paint then assemble a plow? I'm thinking even with epoxy it makes since to prime/paint assemble. The only only items that would not me painted would be the bolts and nuts. I see the hardware paint being damaged during assembly

Check out OxyStyx epoxy primer. It sprays well and has worked well for me. Get it from an outfit called the coatingstore.com. I use every way possible to get the rust off... wire brushing with 4 inch grinder/brush, scale gun and even electrolysis on some parts. Get it clean, clean.

What is wrong with the farm store paints? I am going to paint some tractors but don't want to bust the budget as they are not going to be shown or displayed just used. There are so many opinions I am confused. Thanks
