What you can see here is the driver's side, top corner, which is in a horrible state. The part that will replace it is actually not at all bad, which is surprising when you consider that it has been sitting in a field for over 40 years, where mine has spent a lot of that time indoors.
I have also been rubbing down all the windscreen surround and front panel frame ready to take POR preparation and filler/seam sealer, which is on order from Frost. I have also been in correspondence with the manufacturer in the US and am really investing quite a lot of hope in their claims for the products.
I will report back on the results.
