"Great Stuff" expanding foam ????

Regardless of product.....you can simply buy a cheap can of spray paint and have any color you want. I have done this on several projects.....paint and foam has lasted years.

I have 4 20,000sqft barns. I am trying to tighten them up and make it easier to heat. 6 foot eves. I was looking for commercial equipment. As I know of a few more guys around that maybe interested in it also. They all have more barns than me. Figured it up and I was going to need 33 of the 600ft kits just to do one. That's like 30k. Needs to be more cost effective for me.

With that much, you certainly aren't going to do it out of cans or the 600 ft kits. Cheap prices for a big job like that are in the $1-1.25 a board foot range so it still won't be cheap. I'd still call a couple of contractors for pricing and once you have something as baseline price, you can figure out if buying the equipment and splitting the cost between the bunch of you makes sense.
