Not a new thread ,I ask some month back . But no clear suggestions were mentioned. I have now burned throw almost two of three of my last jars of Testers acrylic flat clear and it is getting harder to find and higher priced. I would like to know if any body has found a similar flat coat ( same flatness , if that is a word) in another paint brand. For air brush. I have used micro scale flat clear and it works ,but still seem to have too much shine when I am weathering a project.
