Thank you kindly -- was going to have my automotive paint supplier Sherwin Williams mix up some based on the color, but really don't trust the fact most paints don't like high engine heat. The original JD greens on my green tractor engines are doing absolutely great -- two are 10 plus years old and in great shape, one is a 1966 (JD 2510) and its paint is darn good for its age.
I was surprised when the dealer told me Sherwin Williams owned John Deere paints, but Sherwin really gouges you on paint. I have an old JD 318 I'm restoring and hope to keep it close to factory quality -- and that obviously says stick with the original. I've done these engines in black but the greens seem to "pop" better........
