So I ended up getting some of the Four Star Tire Gel while it was (and still is) BOGO at autogeek.
I have to say... I like this stuff a lot. This stuff leaves a really nice deep matte finish, exactly what I was looking for. It's not shiny at all, which is good. I didn't really even let it soak in for a very long time when I used it, but it's held up to a few days of rain extremely well. I'm very impressed. Which is good, because I have 2 bottles of it to use.
I'll try to get some pictures of it later. But it gives a very similar appearance to the Ultima tire protectant.
