I have used this Rustoleum spray can a couple of times and never had a problem with it until now. I warmed the can and shook it for 5 minutes. It sprayed ok for 2 seconds then clogged. Does anyone know the wire size to clear the nozzle? I soaked it in acetone and blew it out with 100 psi and it just instantly clogges again. Is there something wrong with the paint in the can. I got some paint out without the nozzle and used a brush to paint with but I'm trying to get a spray coat for the final finish. Tried other nozzles and got the same results.
Thanks,
MM :)

The new Rustoleum cans are designed to spray upside down as well as upright. That means that you cannot clear them by spraying upside down like you used to be able to do. It's not the nozzle that clogs up, it's the tube inside the can. I think they did it to sell more paint since the cans will clog up long before they are empty unless you use the entire can in one session.

I've used both the "old" can/nozzle and the "new" nozzle Rustoleums. I prefer the control and lower flow rate of the old version. As regards clogs, it has always been an issue as far as I'm concerned, so when I'm done, I always remove the nozzle and soak it in mineral spirits, then blow it out. I never measured just how big the hole was, but I use leftover Mouse race line clippings (.010 solids) to poke the holes in both directions. The hole is actually bigger, I believe. I also swab out the top of the can with the nozzle removed using mineral spirits and store it that way. Having a glump of dried paint break loose when you reinstall the nozzle seems like a good way to achieve the problem you described? There may be better techniques, and I don't claim to be a painter.
I really like their Maui Blue, though....
