My fermeter is a bucket - the lid has a rubber O-ring for sealing. I would like to get some keg lube to apply to the O-ring to improve the seal. The plan is to apply a thin coat of keg lube and then dunk the O-ring in Star San, then put it into the grove in the lid. Is keg lube the sort of material that will stay on the O-ring when dunked in Star San?
