so I was sitting there wondering what to do as I hate shakeing bottles by hand or stiring them up with a toothpick...
and as I sit there low and behold mine eyes rested on my cordless dremal and that little lightbulb went off over me head...
I fit a toothpick into the drill took my hobby knife and flattened off 2 sides of the toothpick and stuck it into the paint.. and volia.... instant do it yourself paint mixer.. at 15000 rpm it mixed up the paint in just a few seconds.... and clean up was a breeze.. just throw the toothpick...(not the dremal) in the garbage... (also helps if you cut off the bottom point of the pick....

p.s. used this to mix up Model Master enamal paint that was seperated a bit and it did work well :>
