Brian,
to remove the front glass just take a razor blade round the perimeter stayin as close to the glass as ya can (you will be gettin a new one anyway)..then with a helper just pop it out from the inside with a catcher (YOU) on the outside and lay it away safe on some carboard for the future.
As far as your Frame there are lottsa opinions...POR15 works great on frames ..do a SEARCH on "FRAME PAINT"...you will find lottsa opinions an info.
By the Way..NICE FIND!...enjoy your project!
Tim
