The paint used a primer for best results, but I only primed bare metal. Its probably not a problem to sand off, its not imron or some other kind of epoxy. We just got the thing bolted back together and fired up this evening. I hope to have some links of before and after tomorrow.
Some of the paint I thought i had on there nice, but it sagged later. I could stone it and polish it but its a tractor so its more than good enough. At 15 ft it looks as good as any other.
My last experiment with paint was Zero Rust with the crystal clear coat. I had problems with their clear. Perhaps a better clear would have worked mucy better. This was on my 59 which I later scuffed (as ZR is an excellent primer - no rust throughs) and shot PPG DAR (Acrylic Enamel) red on it later on.
So its been kind of a debate whether I would stray from standard paint or not.
