My 2 pence. Get it sealed, install the MM's and play it. If you want to preserve it then just play it to yourself, don't gig with it.
I have difficulty with the whole showpiece thing. On the one hand a great guitar should be preserved, but on the other a guitar is made to be played, and if it's not it seems a bit of a waste.
Good catch that man, play the sucker and be proud!
