Product works great as intended. I wish shelf life after opening was longer because I only mix small batches of clear at a time. After some months, even when closed, contents will harden. I'm sure product is not intended to be used in the way I use it, I mainly use for model painting and not frequent enough to get to use the whole can. It probably last 9mos or so the way I use it. Just wish there was another way to get in smaller packages.
