Mohwak / Behlen makes a great finish. Many of their products are nitro lacquer, which is great but also tricky. If you want true "lacquer", Mohawk is about the only product out there. They sell it for touch-up and refinishing purposes only. For blending and repairing damaged finishes. The old lacquers have so much VOC content (40% ???) that their commercial use is largely bannd in the US. Rattle cans of it cannot shipped air freight. The solvents are so pervasive, that subsequent coats melt into the base. Too much at a time, and you risk melting the entire finish like an ice flow breaking up. Lacquer dries very thin. It dries very quickly, but cannot be cut and polished for quite a while.
That said, nitro colors, toners, and clears have a look all their own. For vintage pieces, they look "original" just painted. Nothing at all like it was rattle-canned. The finish has depth, not like a solid coating of plastic. I use it on antique fans with great success. On guitars, it is a premium finish that you will pay dearly for. Fender, for example, shoots their top dollar USA guitars in Mexico, since doing so is not allowed in the US. You can wet sand and blend the finish as much as you want. Down side, it is a tricky process. Not a shoot-and-scoot deal. That, and the fumes are extreme.
You can buy many of the Mohawk products off the shelf if you live near Hickory, Winston-Salem, or Greensboro. Klingspor Woodworking Shop has tons in stock; all of the woodtones for sure. If you need something else they will order it for you and you can pick it up in a week. Great thing is the price is $6.95 a can. I believe Mohawk will let you order direct. Otherwise, it can be a bit expensive to order from a custom finishing shop.
If I were doing modeling, I would absolutely use the Mohawk and experiment with full colors, toners, and clears. The result is night and day superior. I highly recommend trying it. A couple coats of toner and clear on, perhaps an airplane model, would probably look awesome and quite realistic.
I believe some of the Duplicolor touch up cans are old time lacquer as well. A throwback to the old car finishes. Some folks use them on guitars, I have read. The little Testors cans may be lacquer as well. I recall how much they stunk up a room many years ago.
For basic spray paint, I am using the Rust-Oleum 2X stuff from Wally World. It is so easy to use that even a WalMart customer can do it. Going back to the OP; yes spray cans have improved. It is almost impossible to screw that stuff up.
