There was a product release last year from Precision Mix Systems. It's a set of plastic bottles, syringes and cups It works fitting the cups to tamiya, gunze zanyo, mr color, ect bottles and using an adaptor to couple with syringes. You just suck the paint out the bottle and mix in acurate parts.
I'm having trouble in getting this product around my town .The company website seems to be down, and there's no online hobby shop that may sell it. Guys, any idea where I can get it?
