Great Stuff Pro 14 Foam Dispensing Gun

High quality, performs well. Expensive. Must have for any foam application construction projects since you can use the foam at your own pace without it spoiling (typically with regular cans) and reduces foam waste. Hard to find cans of great stuff pro at the hardware stores (Amazon does not sell it)

I used it once or twice and it worked fine later on I try to use it again and for some reason the foam was not coming out! Gave it a deep clean and no changes, so I thought maybe it was the foam so I try a different gun and the foam was not a problem , turn out the gun was not working, it was a good gun and it work but losing it once or twice it's too much for it,

If you are doing a few windows, this is the way to go. It's worth the money. You save on spray insulation, easy to use and clean up.

So far so good. Works as advertised. So far I have not wasted any foam cans like I have done in the past.

I like its durable build. Works better and longer if cleaned after use.
