Is 2 sec enouf for an ignition???

i have a spud gun of pvc the combution chamber is about 25 centimeters and my barrel is about 45-50 centimeters But the question is if i put hairspray or deo in my chamber and i close it and i press button to ignite(bbq igniter) nothing happens but when i open the end-cap and i ignite fire comes out...
