custom glass and bonding

Flat laminate can be cut to size or you can have single plate glass toughened. It's not that expensive.
I have converted many things to bonded glass or Lexon (tough perspex) by painting a neat obscuration/black band around the edges. Best one was a Ferrari 350 Modenas track car. Tail gate came to me with smashed window. I cut Lexon to size, Painted black band using "special primer for windscreen glue" & bonded it to the tailgate. I even cut some vent holes in it. Customer was delighted.
You will need to paint a line of primer on the car also using primer supplied with windscreen glue.

I've had 2 flat glass laminated windscreens made for my last landrover offroad racer . Cost me about £90 he came to me templated it. Cut supplied and fitted it.

On some modern vans they seem to have a small sliding opening section in the middle of the glass.
Any ideas if a glass place could Supply that king of thing?

Unless youve seen replacement glass panels with the sliding window fitted for your specific vehicle then you probably wont find anyone who can supply that.
Glass wont bend once its been made. Not much anyway before it cracks (plate glass) or shatters (toughened).

On vw type 3 fastbacks the pop outs bend the glass. Its HUGELY off putting to watch or use!!

Thanks for the tip on the sliders, ill not bother taking that idea further then.

He came and templated it. Then brought the windscreen back a few days later and bonded it in

Who did you use? Someone local to you?

I'm also interested in getting a panel with a sliding section after seeing a T4 with one. I guess getting an existing one cut down to size is impossible, due to it being toughened glass?

Thanks
