Single stage paint

I wouldn't ask but going crazy searching the subject.

I've seen all sorts of opinions on various paints, good and bad or both on each paint.

So, what is a good paint, single stage urethane (or polyurethane?--difference?), black, quick drying, foregiving and paint cost is not an issue (but don't want to overpay).

I just have an old Isuzu truck that's ready for paint...I'm pretty good with my HVLP gun.. it will be my first time.

(I have some spare parts to practice on first).

I've seen everything from the paint on Ebay to PPG, Dupont, Kirker, Sherwin Williams? (they're close to me).

I'd like some folks to just tell me what to buy and I'm out the door to do it.

Thanks.

(By the way, I haven't seen much on Sherwin Williams paints on google....stay away?).
