      Changed formula?
      I’ve used Alex Flex consistently for the past 5 years with great results, but the 2 most recent tubes I’ve used have been different - and not in a good way. They are very soft, almost runny and they take 3x as long to dry. They seem to shrink more than usual as well. I dont know if i just got a bad batch or if this is a permanent change, but I’m going to have to find another product to use going forward.
