I used some a few week ago. I didn't have a problem. Be sure to have plenty of space covered for the over spray if using inside. It's a chore to clean that up. I spray baste on two pieces of plywood set on top of saw horses. DH has the lightweight stands and he put handles on the plywood so I can move it easy if he isn't here. I clamp the backing to the wood and lay the batting on top, spray the batting then turn it over and smooth. Spray the batting and smooth the top on the batting.
