One of the fixed rear windows on my SD1 is leaking and I'm hoping to sort it properly, which will mean removing it and checking the condition of the paint etc behind the rubber. It's mounted in a conventional rubber seal which appears to be in good condition although of course it may have hardened over the years. New ones are readily available, though.
The workshop manual recommends 'Seelastik' between both glass and bodywork.
Is this still the best thing to use?
