This foaming sealer is perfect to seal the corners of a metal building. This Summer is really hot and decided to a/c my woodworking shop. Sealing the corners of my shop effectively is essential!!

Used to fill hole in wall. Large hole, needed a stiff surface to patch. This helps, just doesn't go where it's aimed, straw doesn't stay attached. Very messy. ;However, it did help put a more solid surface for patching.

I was not able to figure out how to reuse the straw. So while it worked as a component in my efforts to fix a golf ball sized hole in my siding (caused by a golf ball!), it was a big can that I could only really use once.

I've seen the same thing other reviewers have seen: The seal between the nozzle you attach and the can is horrible. I put it on as tightly as I could, having already read about people having this problem, and it didn't help at all: Almost as much foam came out of the junction as came out of the nozzle.Not only does this create a huge mess, but unless you quickly clean it up well, the can is wasted because you have hardened foam all around the outlet.

Everyone complains about the plastic nozzle, so buy Picowe tool and be satisfied. I used the this tool, OSI foam and OSI cleaner. My secret is to turn the brass adjustment knob until it is clear "in" (clockwise), then back it out a turn to get a small bead when you squeeze the trigger. I wet my window frame first before applying my bead. For clean out, swap the cleaner can for the foam can, squeeze the trigger, and watch it blow out the foam. Then take the little nozzle that came with the cleaner can and externally clean up the tool. Finally, squeeze the trigger of the tool again to relieve some penned up pressure. So slick. Enjoy!
