Tested some of my old resins before ordering new ones, and I think it's safe to say that this one should not be used any more. Unless for very specific purposes, like doll-sized milkshakes. (Not every craftster out there, newbie or not, seems to know that PU-resin usually has a very limited shelf life. It does not like contact with air, especially humid air. Even if it still looks fine in the can/bottle, even if you screwed the lid on reeeeeally tight or even vacuum-sealed it... Sometimes this just happens. Yet there's also resins that age rather well despite being badly stored, and cure properly even when the individual components start to get flake-y or crystallized. Sometimes a resin can even be one kind in this batch and another in the next. My advice for both old and brand new resin: Always run a little test before pouring it into your mould!)
