Spray Vallejo with 50% flow improver and 50% paint. Sprays like a dream. I personally like Ammo paints but I use Tamiya, MRP, Mr. Hobby… I used to use MMP but it’s like a science project to get those things to work properly. I have a lot of inconsistencies so I sold most of them. Createx makes a much better thinner for MMP. I think it’s the 4011 reducer. Its way better. I just bought a few bottles.
