Pre mixed paint question

[cheese9988]

Dumb question, if your going to have to refill your paint cup a couple of times while shooting and you want to mix a batch of paint/reducer/hardner to suite your needs, how long will it last like that before drying? Keeping a lid on it of course. Hours/days etc?

Shelf life varies, if you are going to divide it up make sure you shake it really well first so you get equal flake distribution. Un catalyzed base should last for a long time... like years, if you add your hardeners/catalysts I would say a few hours tops if in a sealed container just to be on the safe side. For clear I would say less time 1-2 hours.
