This powder stuff says its for perminising the ink as well as staining, so if I want an out door mix its smart or dumb to add this shit. PP or whatever.
Whats the best type of container to put thinned out oil based paint into, I use random jars like apple sauce jars and such and it seems like they dont close tight enough, the paint starts to harden in no time.
you have to put the mustard powder in first before the acrylic. When I think oil based paint in a few days the oil and paint shit sepprate so I shake it again and it seems fine but its pretty gay.
