I wish that some paint manufacturer would come out with a rattle can that won't clog up or quit spraying with half a can of paint left in it. I can't tell you how many half empty (or half full) cans I've thrown away because they wouldn't spray. I even turn them upside down and spray a little air just to clear the nozzle but that deoesn't seem to help. I've tried them all, Krylon, Rustoleum, Valspar, etc. and they're all the same.
Sorry for the rant but I had to get that off my chest.
