I've also found the Rustoleum spray cans to be more prone to clog anymore. I've tried various things, From soaking out the spray nozzles in laquaer thinner, but they usually just reclog after a short spray again. The paint product has changed anymore, thank the Government for that....
I've even tried storing the used spray cans upside down, but it doesn't seem to guarentee anything either.
The quarts seem to be better lasting protection than the spray cans are. I use the quarts thinned with about 30% mineral spirits in a small spray gun for some jobs. It sprays on just like any enamel paint. Keep the coats light, allow to flash off 10-15 minutes before applying another coat. Allow to dry a few days before top coating with a Rustoleum Top Coat.
They have also made the spray cans smaller now, what use to be 12 ounce are only 10 ounce cans now. They "bowled" the bottom of the cans up in, still look like the 12 ounce cans....
