Don't buy great stuff - buy this
After going through about 6 cans of great stuff and getting poor results, I decided to give this one a try and it works great. I'm insulating some panels and great stuff doesn't expand well, this does.

Well worth it
Two cans for the price of one, great value. When I used it on the edges of the house (about a month ago) it has kept out the drafts and I was able to paint over it. So far so good. Only negative I have, it is hard to clean off bare skin, I would still use this product again though.
