The can isn’t properly warmed up/shaken plus you’re spraying it on too thickly and in humid/wet weather.
Make sure you shaken your can thoroughly for at least 30 seconds to a few minutes. If your layers are still shiny I would then use hot tap water in a mug and stick the can in it to warm it up.
Depending on the weather, I find I have to lightly mist at least a foot and a half away from my doll to prevent it from becoming shiny, and in very light mists. Do NOT go any closer than a foot to help it not be sprayed on too quickly.
A light mist would be like imagine spraying some perfume on a high class lady. You don’t wanna drench the woman.
You don’t even want to see the msc on your doll after misting it except for a slight sheen.
In drier weather, you could spray the doll and have the doll be wet looking and it’ll set fine, but if your MSC is turning out shiny you need to be very frugal and do multiple layers especially for a base layer.
The surface texture you’re aiming for is like…. polished wood? high grade artist Paper?
Anyway if you’re super attached to the face up you’re already doing and it’s shiny, I would put the doll aside for a week and let it cure fully. Usually after a week, the MSC turns more matte and then I can gently mist on more layers to make it truly matte cuz I ain’t scrubbing all my hard work off lol.
You’ll get the hang of using MSC and can skip these steps once you’re more used to hearing/feeling the metal ball inside the can and how it travels through the chemical.
But yeah, I know it’s difficult waiting and waiting but I have not found any other shortcuts that can shorten the time at all otherwise I would be telling everyone lol.
I learned something recently about shaking spray paint cans: When you start shaking them, you’ll hear the mixing ball inside make two distinctly different sounds. When the ball is at a point where it only makes one sound, then the paint is completely mixed. (And of course you have to keep shaking it periodically to make sure it stays mixed.)
