Harbor freight has a mini hand pack grease gun with aa fine tip for $5. I bought a bulk pack of yamaha marine and use it with this baby. To load, put on a rubber glove and use a plastic spoon. It works well for bearings, and i use a jar of grease and a brush for most else. Its plenty for a part timer like me.
