I recently picked up some new ironlak cans. I forgot to shake them before use and sprayed in air to get a feel of the pressure. Now my can won't spray at all. Nothing comes out. I tried a new can and shook it, and it works just fine. I went back to the ruined can and shook it for ~3 minutes. Still nothing. Its a brand new can so I don't know whats wrong. Did I clog the cap? Did it run out of gas?
This has happened to me twice, I only figured out what was up last night- hopefully it's the same issue. Try twisting or pulling the cap off (without breaking it) or just loosen it slightly, it should start working immediately. I hope you read this before going caveman on the can
