Going to need some help on this one.

Left plane for two nights parked outside at Reno.  The canopy was completely covered.  No snow and temperatures remained above freezing.  Returned to find a crack in the center of the bottom of the windshield, extending vertically about 5 inches. BUMMER This plane suffered a traumatic incident back in 2003 when the gear folded during takeoff at North Las Vegas.  In addition to the gear, engine mount, and wing damage, a cracked brace behind the firewall in the nose gear tunnel was replaced.  This brace turns out to be directly under the windshield and the original stress on the brace could possibly be the cause of the resulting windshield crack even though it took several years to appear.......MAYBE.??

Anyway, this plane has had pressurization problems from day one;  with 2 psi being the best the cabin has held so far, so I dont think that the pressure could be the cause of the crack even though it might have helped it along......MAYBE??????

Anyway, since I have no real experience with Plexiglas, I am hoping to get some help from anyone on the LML. One possibility that has been discussed is as follows:  Stop-drill the crack.  Apply an inverted 'V' shaped C/F patch at the bottom of the inside of the windshield to cover the crack;  then drip some commercial windshield sealer down into the top of the crack on the outside;  followed by another similar C/F patch on the outside of the windshield. Does anyone think that this fix might work??  Anyone have any other ideas?
Appreciate the help.  Regards, Bill Hogarty
