I don't know of any truly matte finishes.

The only ways I can think of to make them matte is to either lightly sand them after the last coat, or dust them lightly with talc or powdered chalk (calcium carbonate) when they're still damp. And the last could be rather tricky -- try it on something that's not important, first.

Test a sample first on something that doesn't matter.

Autumn, thank you for posting. Late information is better than no information, so if you know the solution to a posted problem, please post, even if it's a very old post (even ten years!). If something is a problem for one person posting here, it's likely to be a problem for many others who check out these forums and don't post.

I, too have just recently tried the matte varnish. I was speaking to the clerk in the hardware store, and he cautioned me to shake the can really well, longer than you normally would for spray paint.  He said that the stuff that makes it matte settles in the bottom of the can, and for the best effect, it needs to be completely mixed.

He said this fact especially applies to the newer glow-in-the-dark phosphorescent paints, both the spray and the liquid. He suggested mixing them at least three times as long as other paints. If you don't get the glow effect, you didn't mix long enough.

Good luck!

Sue
