What does 'flash' mean in that context? Let it dry naturally?

Only two coats of clear?
I know it's 2-pack and doesn't often require flatting and buffing, but 2 coats still seems a little on the thin side! I read 'flashing' to mean drying naturally. Should be obvious with most bases - glossy when wet, satin when dry.

I think flash means let the solvent evaporate, but not the polyurethane polymerise ie 'set'. If you touch masking, if it strings then you're ok

Looking at that thread on which paint is best and the response from KDS Keltec who run a high end bodyshop in Kent, the best finish it achieved when you paint and clear coat, then flat, clearcoat again and then wet sand and buff to get a mirror finish. This is often called 'Flowcoating'
This gives an good paint depth without 'solvent pop' that you get when apply too many coats and the solvent can't escape' leading to a dull finish that takes years to stabilise Here is a demonstration https://www.youtube.com/watch?v=ViT9z-zrJJU Then buffing https://www.youtube.com/watch?v=ve_9IBW78uo

I contacted the chap in the video, "The Gunman" - he said 2k epoxy too and that that is also what they used on aeroplanes.
I have ordered some PPG UHS lacquer and reading the fact sheets, it requires 2 coats which gives a 60 micron thickness. I'll then flat and give another 2 coats to enable a 120 micron thickness of clear. I'll do a separate post, but I'll need to wait until the weather warms up to between 18 and 25 degrees. It seems that PPG is one of the top clearcoats so I'm quite looking forward to how this turns out!
