Default Re: Glass Wind Wings

Putting a mechanical fastener through the glass will keep the glass in place, however....

If your glass is tempered glass, drilling it will reduce it to crumb sized pieces. You will need to have the holes drilled in the glass prior to the tempering (heat treating) of the glass.

If your glass is laminated glass, it can be drilled, but there is a chance of the glass cracking at the hole from the pressure of the hardware squeezing on the glass. A hole in annealed glass is a weak spot.

Perhaps using an adhesive in place of the rubber pads. A rear view mirror adhesive may provide a near permanent bond. Others may chime in with experience in this matter.
