Like any specialized field, mechanics are full of opinions relating to how they should do their jobs. We can't even agree on being called "mechanics!" I like working on classic cars, so I'm fine being a mechanic. People that work on later model vehicles seem to want to separate themselves from the wrench turners of days gone by, preferring to be called "technicians." Mechanics and techs can argue over anything. Whether or not to wear gloves on the job doesn't escape debate, either. I prefer the safety of a glove. There are so many bad things that can happen to your hands when you're poking around, in or underneath a car. Gloves are also good idiot insurance, like the time I had a wire brush attachment on a 10,000 RPM grinder that jumped off the frame rail I was cleaning, right into my other hand. It chewed the glove to pieces and wound it like a cheap watch, but my hand underneath suffered only minor scratches. On the other hand, some techs say they can't feel what they're doing when they have gloves on. I see their point, but when you get used to gloves it doesn't seem to make a difference. Safety first, I say.
