See!
Now this is why I don't like Acrylics. You either have to use proprietary Primers and Thinners. Now, what about this too? There are so many brands and brands cousins out there. What if, for say health reasons, you, cannot spray, You brush right? What about coverage in the scenario. Back when Testors/Modelmaster brought out their Acrylics for instance. It was a situation where the folks in the rec.room where I worked as a volunteer, could not spray. The Acrylic covered terribly, Required more than one coat and tried to lift when a second coat was applied.
I have had this problem with Tamiya Acrylic. That's why my Akagi never got finished! I guess I will have to go back to custom mixes from the Testors square bottle Enamels! I know environmentalists( Can't Blame them here) were the drive behind this. The reports of sick children from chewing windowsill edges that had old lead content in the paint. Who lets their kids eat the windowsills anyway? But, it has gotten out of control. Even outside the hobby I have painted sections, outside my house, with, I might add, supposedly good brands of paint, to have paint running down to the sidewalk and driveway from the rain. They cannot seem to make it stick worth a darned.
The last part is this. I have gone to acrylics ,Straight from bottle with the Mig Jimenez brand, and their Ammo line. It's okay it seems, and I have thinned it with filtered/ distilled water with NO bad results. Maybe I have found a new brand to love? Here's hoping!
