Hi Roon, As far as I know (never actually used it) the OEM tractor enamels are synthetic (or alkyd) enamel and not acrylic. The only way you can be sure is to check the label information. This would be the low end for enamels, typically costing about $25 or $30 per gallon. A step up would be an acrylic enamel which has a little better fade resistance. This typically (without hardener) would be in the $50 per gallon range for an automotive paint. OMNI is a line of paints in the PPG automotive line-up that is commonly referred to as an "economy" line, at least compared to PPG's higher end products. That doesn't make 'em BAD, just that they would be in the $50-$100 per gallon category rather than the well over $100/gal "better" stuff. OMNI is available in different chemistries. You can get it as a single stage acrylic enamel (OMNI MAE), a single stage acrylic urethane (OMNI MTK) and as a two stage urethane basecoat/clearcoat (OMNI MBC). My own recommendation, especially for a working tractor, would be to opt for the better fade resistance of the OMNI MAE acrylic enamel ($50/gal) over the OEM tractor stuff. It costs some more but, IMO, it's worth it. You could also get into the urethanes as a more durable finish still for about $75/gal and up (in OMNI), especially if someone else is doing the painting and you don't have to concern yourself with the health-safety aspects of that particular chemistry.
