Hey there Greasy John, I used a Sharpe HVLP gun and PGP's acrylic urethane for the top coat. I used their epoxy primer for the base coat on everything. The grill, hood, and gas tank got several iterations of bondo, sanding, then a sanding primer over the top. I made sure that I put the top coat on within 72 hours of the epoxy primer -- apparently this will help the two coats bond together chemically. After that time, you'd have to scratch up the primer coat so there would be a mechanical bond between the coats. A lot more work, eh? Actually, I put the top coat on only an hour or two after I finished the primer, at least on the chassis. I also pulled *everything* off the tractor and painted in separately. That made it easier to get a good glossy coat all around things like the oil filter housing, the fan blades, etc. The chassis is pretty easy to paint...the roughness of the cast iron makes it almost impossible to run the paint on. I found it much harder on something like the hood, which would have a vertical side no matter how I positioned it. I had to be really careful to treat the verticals gently...the HVLP gun will put out a lot of paint. I found two things were really important -- first, I spent *a lot* of time working the metal before I painted. I think I probably did 4 or 5 iterations of bondo/sanding/primer on the sheet metal before I could be certain I had really gotten it smooth. Second, I could have used twice the amount of light in the garage when I painted. It got really hard to see when I had put on just enough paint to get the shine. I wear glasses too, so trying to see through the paint fog, safety googles, and my glasses got really hard at times... Hope that helps! - David
