Hell, at least you remembered to thin it at all...
Awhile back I had all my M1A1 road wheels off the sprue, cleaned up and glued together and after all that, all I wanted to do was start shooting MM flat black. Took me about 5 minutes of scratching my head and wondering why it was barely flowing and what did come out was all thick and clumpy...
Gave me an excuse to break the 360 down for a full blown-cleaning I guess
