Cleaner players

[Taylor]

I am having trouble painting clean players with my apple barrel paints. Especially custom players. Here are a couple of pictures of some guys i painted up recently, they aren't completely done though. I have to untouched poses in my basement and they look really clean with the paint job. These guys look terrible, or at least they aren't at par of what I would like. I usually either paint right out of the bottle with a small brush, or squeeze a little out of the bottle and then I put delta ceramcoat acrylic thinner in and I stir. This still isn't working. Can anyone tell me what they do to prepare their paint and players so I can get better results? Also what can I do to improve my players?
Thanks, send a pm or just respond right here.
