I have an area behind drywall in the basement that I wanted to seal against occasional water intrusion, and didn't want to run through several smaller spray foam cans to accomplish the job. So, while searching for something larger, I came across this set, which seemed ideal.Upon receipt, I was delighted with the mega-size of the cans. This was plenty for my needs. However, I didn't read the description closely enough to realize I needed dispensing nozzles. So, I returned to Amazon, where I found a set of 12 disposable nozzles by the same company. When they arrived, I was ready to rock my project!What do I think of the results? Unfortunately, I applied the foam in an area I can't reach to take a photo. However, the inevitable droplets of foam that accompany my projects looked great - nice and dense.If you have a large foam project, I highly recommend this kit. Just be sure to pick up some nozzles at the same time:>) A bonus of the disposable nozzles is that you should be able to use part of a can, remove the nozzle, and save the rest for later. That's my theory anyway, and I intend to test it soon.
