A grease gun can be a handy tool for the home mechanic because car parts often need to be greased to reduce friction and increase the life of the part. A grease gun can inject grease into areas that are difficult to reach. Using a grease gun can be easy once you have taken it apart and loaded it. By doing this, you immediately see how the gun works and you are ready to use it with no further directions.
