My car is being done by a spray painter.

I did check this out yesterday with them as my car is halfway reasembled now.
My front and rear windscreens were cutted out in the rubber around them.They then cleaned out the part where the windscreen was. I bought new window rubbers as they of course cutted the old rubbers and I could'nt use them anymore.
The new rubbers are not adapted for the chrome strips that were fitted at the factory.
So my rubbers are without the chrome strips front and rear. It is a bit bad but nothing I can do about it now.
I think you are also going to lose those strips.
The window came out without any problems.Remember. It is a Datsun.
