Yeah, by the time you smash the brush and press-N-seal around it, pretty much air tight! I usually throw it on the kitchen table, micro wave shelf, sink counter, you know, anywhere really. I forgot about them on the sink in the basement before and came back like a week later and started painting again. Only draw back is about after 4-5 restarts the brush is pretty bulked up with paint around the collar and needs to be washed out anyway!!
HEY, I KNOW WHAT YOU GUYS ARE THINKING BUT, Uhhh I was just painting the house cause no one has dropped off cars yet! Contrary to poplar rumors ABodyBetty did NOT TELL me to paint the house. I Swear!!!!! LOL!!!!!!!!!!!!!!!
