I still hope I never get a stash any larger than a dozen (or so...). However I have come across one advantage of having some sort of stash, which is giving me some lead time in buying paint. I started another thread a while back about having airbrushed model paint for the first time. I have just done a small amount of airbrushing on my current project, and only my second time using Tamiya acrylics. While it is more difficult to clean up, it certainly covers much nicer than the artists acrylics I have been mixing. This was their XF-60, Dark Yellow, and it went on like a dream.
So maybe I really do need a stash
