Yup, the old nitro lacquer was a long time ago, just like synthetic enamel. See here for a crash course in basic paint chemistry/history. There should be nothing wrong with the Martin Senour paints carried by NAPA. My local NAPA has that brand also. I've never used it but would consider it equivalent to similar products from PPG or DuPont. Like those bigger paint suppliers, Martin Senour has "lines" of paint products. I believe their "value" line is called Crossfire. Again, I've never used any but expect it be an equivalent competitor to PPG's OMNI line or DuPont's NASON line. I see at their website that they have all the typical products in Crossfire. Epoxy primer, a urethane surfacer and acrylic enamel and urethane topcoats among them. You can get the detailed technical data sheets for any Martin Senour paint product here. I see they show several different codes for John Deere green. You can see those listed here. As is typical of most tractor manufacturers, apparently JD used more than one shade of green over the years so I have no idea which one you would want or even if you'd be satisfied with any of them. But that is true for any paint manufacturer, including whoever (Valspar?) actually makes the paint you'd get at a JD dealer. You'd have to investigate the actual color shades with someone who is familiar with the green JD used in the year you are interested in. The JD forum at this site would be a place to start. Or maybe one of the JD enthusiasts will jump in here to assist in a decision. I don't have to be OK with whatever paint you decide to use. I just think there are better options out there than any tractor dealer paint, including that from JD. I mentioned PPG and DuPont as those are the brands I am familiar with. And I mention the automotive "value" lines as I think they represent a good grade of paint products that provide the best value for the money for any overall paint projects undertaken by the DIY. On the other hand, if you are going to keep the tractor shedded (out of the sun) and only used for parades or some such, then the dealer paint (including their recommended primer) should be satisfactory for you. But if you are going to have the tractor outside regularly, i.e. a working one that sees a lot of sun, I think you'd be far better off to investigate a hardened automotive acrylic enamel or urethane. That's especially true if you already have a supplied air respirator for safe use with hardeners. After all, you don't want that nice green to be more blue than green after a year in the sun. Too much work invested in such a project to have that happen. Rod
