I am planning to paint a tractor with CIH red with hardner. Is this a good paint? How about primer? Is CIH primer any good? Which do you guys prefer? Your favorite combo??
 
If you are going to take most of the tractor down to bare metal I would use PPG epoxy primer. I would rather topcoat it with PPG Concept. Both primer and paint are a lot more expensive and complex but I think it's worth it.

When you use a paint with hardener, be sure you use it somewhere where you can get a lot of ventilation even wearing a respirator. The hardener contains isocyanides which is some really nasty stuff. Some of it will go through a chemical respirator. It's really recommended that you use a air supplied respirator with it but their expensive and not very cost effective to paint one tractor. I usually use the stuff outdoors and hold my breath when I'm downwind from the sprayer. Then the problem painting outdoors is wind and bugs. I've been waiting about six weeks on a project I'm working on for the temperature and wind conditions are right. Pretty soon I will have to wait until summer for the bug population to die down.
 
If you mean CaseIH 2150, it is probably good enough, I have not used it, but others seem to like it. If you mean CIH "red" from some farm store, it is lousy paint. Stephen is correct about the isocyanates. You might paint for years without a problem, or they might get you for the first time. Not worth the risk. If you are painting one tractor use 2150 without hardener. If you are making it a hobby, bite the bullet and get supplied air as I did. Be sure and read the MSDS first, but the catalyst for epoxy primer usually does not contain isocyanates, in which case a charcoal mask is ok.
 
Hobby Air, there are several brands, all work, Hobby Air is somewhat uncomfortable in the summer because it generates warm air -- really not a problem because I only paint a few minutes at a time. For sandblasting it will get pretty warm.
