It's too effective sometimes.
Garage door was getting harder to up and over. Sprayed every bit of the mechanism and left it for an hour. Went out and yanked the door , it shot up clunking me on the chin on the way up. Stunned I clutch at my face , the door then under its own weight began a downward path.As I was coping with pain and my eyes watering profusely I did not notice this change of direction. It smacked me on the top of my head drawing blood.
I locked it and went for a lie down.
