Probably bring the tubes out and squeeze fresh before painting. Or blow dry before transporting in the palette. Lukas is worst that M Graham. However this can be an advantage because the paint stay moist for a longer period of time. I prefer to paint with moist paint. Or use a air tight palette that I am currently using now. The paint creeps inside the palette and stays inside and not into the bag. Not a serious problem though, but unless the user prefers everything to be clean and proper.
