Hi Glen et All..
 
When I purchased our 'Coupe the bubble windshield rubber at the bottom front was so old it was hard.
 
I talked with an engineer at Univair and ordered the proper windshield retaining trim. I also asked what the best adhesive was to do this job. He sent along a 5 oz tube of 3M Scotch Grip 1300 Rubber and Gasket adhesive. It cost about $7.00 US.
 
Applied in the approximate same mannor as contact cement.
 
First I fitted the windshield with the trim to the aircraft slightly pushing down on thebottom of the windscreen to seat the rubber trim, Next I marked the fwd edge of the rubber trim on the upper skin just aft of the upper cowl. Remove the assy, clean a/c area with mek and the rubber trim with alcohol, apply the cement to both pieces (note here that only the fwd half of the rubber trim need have cement applied to it as the aft half has to bend up to meet the windscreen). Apply the ruber trim to the upper fuselage following the guide line previously made, hold fwd edge down with masking tape for 24 hours. Reinstall the windshield in place. Run a bead of cement along the inner edge of the assy (in the cockpit) to fill any gaps and to tidy up the looks a bit.
 
This is really good stuff, and if done well the windshield just sits in the rubber trim and is easily removed for maintenance (changing out side windows)
 
Good luck.
