Ok, first off, I would like to admit that I am an idiot since I am certain that many of you will be thinking so after reading this... Last summer I stripped my Farmall Super H and primed and painted the chassis and most of the cast parts with (get ready for this one) the rattle can "IH red" from tractor supply, which is an alkyd enamel. I am embarrassed to admit that, but it"s the truth. It actually looks very nice, but the more I think about it, the more terrified I become that it will turn pink very quickly. I also had the idea from the very beginning that I would have IH 2150 in acrylic enamel mixed for the tins and apply with a spray gun since the finish on the sheet metal matters much more than it does on cast surfaces. I am also concerned that the 2150 will not match the tractor supply rattle can paint... So my next thought was that maybe I could just shoot the whole tractor with the 2150 right over what I"ve already painted... What can I and can I not spray over the alkyd enamel? I really, really, really do not want to have to strip the paint off the tractor. I worked really hard to get it prepped in the first place and I don"t want it to be for nothing. I"m dreading the idea. Can anyone tell me what I should do here? I want to end up with a nice tractor.... It"s retired and it"s important to me that it"s pretty when it"s done and that it stays that way for a long time. Thanks.
