Too thick to use, especially in the winter
This stuff is so thick, you can't even pour it out of the bottle. It works fine once you get it out, but it's just not user friendly. We even tried putting the bottle in a pot of really warm water, trying to get it to flow better, but it didn't help much. It seems to secure the puzzle pretty well once you use it, but it does make the puzzle curl up some. We put them into poster frames from Walmart, so it didn't matter to us, but if you wanted to just hang it, you might have to do something different. We didn't try putting it on the back, as I've heard suggested. Personally I prefer the sheets that you stick to the backside of the puzzle instead. Much easier to work with, and no drying time.
