Just to satisfy my curiosity and the fact that I had all the ingredients on hand, I whipped up a test batch, a whole 10 ml worth, and I can confirm that it indeed works, at least for Model Master Acrylics, which is the only paint I tried. I thinned the paint to a very thin consistency to test its application, adhesion and filming properties. I’m happy to report that at least to my subjective standards, it checks out fine.
I realize that not everyone wants to play Bryan Cranston’s role and mix up chemicals in their kitchen, but since I had the ingredients and the ability to measure them in minute quantities, I gave it a shot. I too prefer to use off the shelf products, in their intended usage, (sorry blue washer fluid fans), rather than resorting to graduated cylinders, pipettes and Breaking Bad techniques.
Thanks for the video link Wade. I watched it (and remembered why I don’t care for many YouTube videos) and yes, that Ultimate Airbrush Products Ultimate Airbrush Thinner does work. But I guess the only way to get the stuff is to order it from the UK. I can’t find it available here in the US by Google or Amazon.
So I will still need to give the Vallejo thinner a shot, and of course there is always the old fallback of windshield wiper fluid.
A pox on the house of Rustoleum for discontinuing all of the Model Master products!
