How do I determine what propeller model I have?

Where do I get Service Bulletin Information and does it cost anything?
Do I have any airworthiness directives that affect my propeller?
Can I use an alternate material (paint, filler, glue, sealer, grease, etc.) instead of the specified material?
The materials that Hartzell specifies are selected based on extensive testing and evaluation to determine that they adequately perform their desired function while not having any adverse affects to other components or materials used on the propeller. The testing and evaluation has to determine whether the material will function as desired throughout the entire operating environment and envelope of the subject propeller. On a certified product, such as a propeller, the use of the approved materials is required by the FAA.
