Im looking to build a UDS, i just got a food grade drum for free that has the red liner in it, after a lot of reading I'm not too sure i want to take on the daunting task of trying to remove it. I have another lead on a drum that was "Reconditioned" through a local hydraulic fluid distributor. My question is would it be safe to use this reconditioned drum or should i continue to search for another food grade drum which seems to be near impossible here in dover delaware
