My tire won't let me squeeze Slime into it (for a slow leak). I actually put a clamp on the bottle and squeezed it 'mechanically'. I can blow air into it with my air 'gun', and when I put the valve core back in, I can air it up. What's up? I know that slime disbelievers outnumber us 10 to 1, but please try to be helpful. Thanks!
