What have ya'll used to keep the inside of the metal roof on a shooting house from building a layer of frost and then dripping on you after the sun hits it?

Try some 1" or thicker pink foam board.
Bubble insulation would work although it may fall over time.

If you can remove metal easily then lay plywood then cover in felt paper and re-install metal roof....if you cant remove easily then you might could try stapling felt paper to underside of your lath or purlin strips between rafters....or as mentioned, foam board or bubble wrap barrier.

Following as I have this same issue. Although its usually not all that bad.
Bubble insulation. Shiny side up. Duct tape it.
This, except, I'd get the tape made for vapor barrier. I've tried duct tape, but the heating and cooling seems to cause it to fail to adhere over time. You can buy a small roll of vapor barrier/insulation on Amazon fairly cheap. Tape it so there are no gaps, you should be good to go. Also, It's recommended you leave a gap of at least one inch between metal roof and barrier.

I always use a piece of plywood as my ceiling then cover it with the metal on top to keep this from happening.

Ive considered the foam board but I didnt want to trap moisture between the board and the roof. I didnt think of using some felt paper, that may work but ive been hoping someone would have some spray type application remedy.
Thanks for the reply's, Im going to re-asses it this weekend and see what I can get put up.
I may try this, I just talked to a guy and he did this with the spray foam that doesnt expand much, I think he said he used some that was for gaps less that 1". He said he held cardboard up to the ceiling at a angle and then worked his way back and pressed the board up as he went.

I got some of this and used in in my older shoot house. It works, but when it starts warming up it starts making snap crackle pop sounds, not that loud, but annoying.

Anyime I try to use spray foam I wind up just making a big ol mess.
Kraken closed cell spray foam would work perfect for this application. Not sure if that link will work or not. You need one of their guns for it which I have one, you could borrow it if needed. I'm in Burns.
