Its the thirty year rule Pam. If it sits in a hole in your bench for 30 years it isn't dust.

I'm not sure this is what you mean, but sometimes I pre-guess answers because of the drection I need an answer in. You know how it is to ask for help on how to refirb a plane and get 100 well meant answers to the effect that LN has a sale, or why would you us one of those old things, etc... Of course whatever one says, people get to answer as they want anyway.
