Now that's my kind of hotrod!
My second hobby is old Tractors and my 43430s see more tractor paint than anything else. I have painted tractors (my last project was a JD 10-10) with everything from equipment enamel to BC/CC and my 43430s handle them all just fine.
A lot of people may think it somewhat of a waste to use $400 a gallon paint on a tractor but hey, old tractors need lovin' too!!
