As a follow up, if you haven't purchased a spray gun the 3M Accuspray 2.0 system makes handling paint material so easy. The cups and liners can be tossed after you use them and makes for less exposure to the primer, solvents etc.
I also purchased two of these.
I store parts A and B with the mix mates on the can so less exposure to vapors when mixing and pouring. Spin the agitator with a drill, pour the desired amount in the disposable cups using the spouts and you are good to go.
