BUMMER - I have just discovered an inch long ding in the door window of my pressurized L-IV.  It appears to have been made by some sort of power tool and it is deep enough that my fingernail can trace it.  How I have missed it all this time is a real mystery...DUH

Anyway, I guess its fortunate that I am still chasing pressurization leaks and have not tested the plane at 5 psi yet.  My question is....can this be repaired or is the ding serious enough to require replacing the window?  (Do we have any ACRYLIC experts on the list??)  I have never heard of an acrylic repair but I am hoping it might be possible.  Has anyone ever replaced a door window?  (sounds like a monster project.)

Any assistance here would really be appreciated.
