I learned through an automotive upholstery shop that Scotch spray adhesives are not all the same. You have to look closely on the cans to find the product number and go by that, because everything else about the Scotch spray adhesives cans is identical. Regretably, I cannot remember what the number is to look for, it's been a long time since I used the stuff myself.
