Thinking about grabbing some mud and streaking paints. I see Mig has some, as well as AM (aren't they the same company), and Vallejo has some. Any difference in the three? Looking at things like mud splash, thick mud, etc.

I recommend Mig and AK, over Vallejo for streaking paints. AK and Mig split some time ago. Vallejo acrylics tend to dry too fast to work. As far as splash and thick mud, I have some Vallejo paints but have not tried them.

I know Ammo by Mig has consistent and excellent products. They perform as advertised and are not that hard to use.
