Had a can of "Great Stuff" for some time; never had to use it. Pulled it out today for a plumbing job. While securely fastening straw so it wouldn't leak, THE WHOLE NOZZLE BROKE OFF INSIDE THE STRAW. WITH NO WAY TO EXTRACT THE PRODUCT, I HAVE SUFFERED 100% LOSS OF PRODUCT. The nozzle is made of the thinnest, softest plastic imaginable; nice product development, DOW! BTW, there is NO way to register such complaints with them. All they provide is a 'Contact Us' page, which only allows you to get information FROM THEM. THEY DON'T WANT TO HEAR FROM YOU. -Paul in Canton, NY
