I used to work straight through lunch to get cars out faster. After mixing up two customer's repair orders, I forced myself to stop and eat. My afternoon work is much better and I make fewer errors now. A quick ten minute break does the trick.
Customer secured his bumper with cords, and I pointed out the danger. He wasn't happy. How do you handle similar situations?
I had a bumper repair come back after a month because the paint peeled right off, so now I never skip that step.
I kept seeing rust come back on a repair I thought was solid. Turns out, I missed a small spot inside the panel. Now I use a boroscope to check hidden areas before sealing up. It saves me from callbacks and keeps the job right.
