The first time you use it, just take two one yard pieces of fabric, some batting to fit between, and use the spray baste. Use it in a well ventilated area, spray at least 10 - 12 inches from the surface of the batting, smooth to your satisfaction and then quilt.
(Note: do not spray near your sewing machine (or any other machine). The spray is like a wet gas and penetrates through narrow/small openings in the machine chassis.)
If your needle is gumming up, you used too much spray.
