I know only two guys answered my post and thanks for that, but I would like to ask another question. How do you store your paint once it's been opened? I put a small amout in a plastic container to use from some paint I had. When I open my new 1/2 pint cans it will take quite awhile to use them up so they will be sitting for some time. Should I put them upside down or just put the lid on tight? I don't want them to skim over. I'm sure there some old time stripers that have there way of doing it. Thanks again.
