I have a 1938 A that was repainted a couple years ago,(deere paint and hardener). After this years show season I noticed that the area around the radiator cap was starting to discolor and turn yellow, I assume from the antifreeze. The A has green antifreeze that I mixed, not sure what brand. I thought I would try some of this new yellow coolgard II antifreeze in my 1938 G, so before I put it in the tractor I dipped a bracket in some antifreeze and let it sit. So far the bracket has not discolored. Has any one else had trouble with antifreeze staining paint? Both tractors used the same Deere paint and hardener, so I suppose it comes down to different chemical compounds in the antifreeze, causing some to stain and others to not.
