I have three unopened 8# jugs and two unopened 4# jugs of Tite Group.  Lot stickers are getting pretty faded but two of the 8# jugs match and can't read the third but they were purchased at the same time and should all be same batch.  The two 4# jugs are from the same case and match each other but not the 8 pounders.  $300 for each 8# jug, $150 for each 4# jug.
