I bought a pair of mechanics gloves because I was tired of getting new scars on my hands. I even got the slightly more expencive ones with the extra nuckle protection. After a few days of working on my car I have completely worn through one of the fingers. The only good thing that I can say is that I never even scratched my hands when the gloves were on. Overall I'd say that because they only lasted a few days that they aren't worth the money. The best thing that I have done that protects my hands is using air tools. Bolts that I would normaly need a bitch bar for and end up ramming my hand into something, are a piece of cake for a good impact wrench.
