I tried to do my quonset hut 2 years ago myself. Turned out it didnt really work out so well. The product I had tried was called soy-thane, sprayed on via a 2 part cartridge with an air compressor. After I went through a case of the stuff and was completely covered, which btw does not come off anything very nicely, I had enough and sent the rest back. I ended up calling a company called MIG insulation and building. They were actually cheaper than i could do it myself. Should have just called them from the begining, but thought DIY would be cheaper... not the case. Also they were in and out sprayed 3-4 inches on ~3k square feet in about 4 hours. I had spent that long and sprayed about 100 sq. ft.
So if you want my advice, since youre in NY give them a call, and save your sanity, and money.
By the way I also looked into all of the other brands like tigerfoam etc etc. In the end these guys ended up spraying something like 4-55 gallon drums of 2 part product, but there were three guys spraying at a time, with heated guns.
Make sure and do this before it gets cold, b/c when its below 50 degrees F they wont spray, b/c the properties of the foam are severly limited.
