Mr Color GX III

I can not get the right consistance to spray this product. I did like I saw many on YouTube and mixed 50/50 with Mr Color Leveling Thinner. It came out like snow flakes. Then I mixed it 40/60. Mixer was good, but after 3 coats, still not shiny. What am I doing wrong? I use Iwata Eclipse air brush for this.

Edit: I realized GX III is not the product I was thinking it was so backed my message out. I’ve never use this.
