I would go to your nearest Automotive paint supplier and ask them what they recommend. Either Finishmasters, Sherwin Williams auto paint, or PPG auto paint stores. Each of those stores will have their own lines of 2k epoxy and single stage/ 2 stage paints. They should have a couple tiers depending on what your budget is.
I painted my FJ40 in my garage and used Nason single stage paint, provided by finishmasters. I chose single stage because I didn't want to risk spraying the vehicle twice and having to sand out drips and mess up the paint. Spray once and your done compared to spraying the main coat then clear coat.
Just know you will spend $1000 plus for primer, paint, sand paper, prep-sol, etc. You also need a spray gun, air compressor large enough to spray, Take your time, read up on it, and do things the right way. Prep takes a ton of time but it's worth it. Also, follow the instructions to the T. If you paint in too cold or too hot weather, the paint will not adhere right. If you wait too long between coats, the paint will not adhere right. If you don't sand or prep correctly, the paint will not adhere right.
