Oh no should of looked here first

I don't remember paints but I know Dupont Centauri was a common one.

How did they keep it from lifting? Did they seal with a primer first?

I wouldn't worry that much about it. And I wouldn't strip it and start over. The fact that there was a better choice (my opinion) you might have made on the primer doesn't make the choice you did make "bad". I can't offer you any specific advice because I am not familiar with either the exact primer or the topcoat you mention. I assume that the parts that you have primer on have not been left out in the rain. I think that as long as the topcoat is not incompatible in any way with the primer you used, that the result will be at least as good and very likely will be better than the paint your tractor had when it originally left the factory. You have a lot of work invested already, so I would proceed without backtracking. I do suggest you paint a small separate part as a test, just to make sure there is no obvious problem between the primer and the topcoat. I don't think there willl be, but it's a good practice when using unproven product combinations and if you do notice a problem, you can reassess everything at that time. Usually topcoats are applied fairly soon after primers and I don't know what instructions may be noted on your primer can label. Or your topcoat for that matter. My tendency would be to scuff up the primer a little with a Scotch-Brite hand pad (maroon, general purpose), give it a quick clean with a wax and grease remover (for fingerprints, etc.) and then apply your Case paint.
