Restoring a Top Hat

[Parazine]

Question: So were the window channels you used the original and/or from another source?

This was a bit of a problem. I had the original channels for the front windows but the felt covered rubber inside the alloy section was perished. The rear channels were missing altogether. The Seven Workshop stuff is too large, in the end I used a channel from Woolies here:

Single Track Window Channel (woolies-trim.co.uk)

My windows were all recut from 4mm toughened glass as the minimum thickness I could find for laminated was 1/4" (6.4mm). The original glass was 3/16" laminated, unobtanium I was informed but this would equate to 4.76mm, if you could get it.  The Woolies channel would probably work ok with the original glass as well.
The channel was successful, it's just the right size externally and is squeezes up on the 4mm glass nicely. You can tack it onto the wood frame easily as well.
I used a modern glass sealer to seal the fixed glasses and the channel exposed to the weather in. It seems to form a skin but never actually sets. 

Glazing the car took quite a long time
