If you are messing around under the hood of your car, please remember to remove all of your jewelry. Even if your engine is off, your rings and bracelets can catch on pieces of parts that abound in there, causing you to scratch, cut, or otherwise maim your hands and wrists.

Also, to save that expensive manicure, wear gloves when you work on the car. The disposable plastic gloves are ok for washing the car, but they tear up pretty easily if you apply much elbow grease. A better option is those funky yellow plastic gloves that your mom used to wear to scrub the toilet.

If you expect to encounter car fluids, you might want to wear chemical protection gloves. They are very bulky, though, and you might lose some nimbleness when working with small parts like nuts and bolts.
