Found a decent paint for less than a mil ?

I bought some to put on my car trailer and to do the inside and underside of my duster, Have not tried it yet so can't comment on it yet. If i like it I might get some of the semi gloss to do suspension parts. I'm expecting typical alkyd enamel results, as such, I'm expecting the gloss to die back as it cures out, usually within 90 days. I'm kind of funny what I put on the out side of a car as I don't like to put materials on that if I decide later to put better materials on, or repair damage, might cause reaction problems. I have run into to many issues painting over unknown paints over the years. I'd have to look at the can again but I think the Tsc paint is oil based much like rustoleum and thats a mess to put proper materials over. I would step up to at least a catalyzed acrylic enamel or single stage urethane so if you have an issue it can be fixed and repainted without having reaction problems, and you would have better gloss longer. there are some enamel or urethane kits out there for under $100.
