The following procedures are based on my 26 years in the garage door industry. In spite of my high mechanical aptitude, even after 18 years in the business I lost the end of my left index finger. A few years later I had five stitches in my right thumb, and a year later five stitches in my left thumb. In the last year the emergency room staffs have dug steel out of my eye and sewn up my ring finger with eight stitches. The best I can do is help you minimize the risk of injury; that’s all I can do for myself. I am not so naive to think that I have made my last trip to the emergency room. Repairing garage doors is dangerous work.
Why do I bring this up? Cuz yesterday, after a week break, I finally got the second coat of paint on the hallway walls (pause now to break into the Hallelujah chorus). It took me most of the day, in part because I kept having to wipe away the dog hair from each section before I could apply the fresh paint. So now you know. Beware of the Dog Hair Decor!
