I have seen more Auto Mechanics wearing gloves these days. I would think the gloves would make it too hard to do fine work! So why do they wear them?
In the old days, guys called you a wimp if you wore gloves when you worked on cars. Aside from the wimp factor, gloves were too clumsy for fine work. However, Automotive fluids contain caustic or even carcinogenic chemicals(like used motor oil). That's why most auto techs use some type of protection for their hands.
One such glove that has become very popular today is called the Nitrile glove and they work very at protecting your hands. They are made of synthetic latex. They contain no latex proteins and offer excellent resistance to punctures and tears. Nitrile gloves are three times more puncture resistant than rubber and can be used to offer superior resistance to many types of chemicals. Unlike other latex gloves, nitrile gloves have low resistance to friction and are very easy to slide on. There are a few other reasons that nitrile gloves are more popular than other latex or vinyl gloves, including a higher degree of flexibility and superior solvent resistance.
