I started spraying some more frames today with one of my favorite colors, Anodized Bronze (the same kind and color I had problems with last time) using a fresh new can and this one sputtered a little then just froze up completely and won't spray at all. I shook it up very well before I started hoping not to have problems with this can. Can anyone help and tell me if I'm doing something wrong? I ordered four cans of this particular spray paint and so far 2 have given me problems. HELP ME!
