If you are so proud of your machine, then by all means use frame saver (I assume you are referring to an internal coating to protect the frame from rust).
Your frame will get wet inside from condensation if not from rain and water splash.
You can do it yourself if you like. You can get auto body coat in a can and spray it inside your frame. You would have to take the fork off to get at the head tube and access the top tube and down tube entrances.
I would go the extra length to keep the frame-saver coating out of my bottom bracket; don't want it to mix with the BB grease.
If that makes you nervous, have your LBS do it. It isn't a big deal.
