I use a good bit of spray glue running classes or coaching sessions. I print a lot of targets that attach to backers. I also find poster board styrofoam backers a buck each at dollar stores sometimes. This allows me to use standard width range stands to make poor man training backers. The problem is that 3M glue has gone up to 14.95 for a 13.9oz can even at Walmart which is NUTS. The Elmers, Loctite and couple other brands simply don't work at all. This below is under 6$ for decent can and actually works like the 3m does. We don't make a lot of money teaching firearms in the first place. Pennies matter.
