I found a diy thinner on YouTube, barbatos rex channel. Basically distilled water, isopropyl alcohol and flow aid. On a whim I added some createx 4030 intercoat clear, read that here on the forum in a post. I've had great results and it's durable. I've got the the ratio written down somewhere. As for consistency, I go by the "skim milk" rule. Dab some paint on the side of the container, it should run down and just coat, but not be opaque. Semi translucent. Hope this helps.
