Thanks for the response.
I stripped it down one final time and refitted it following EauRouge's advice. The seal seats a bit better now but not a 100%. I have pushed the seal almost at right angles to the grill in one place to fill the gap. It don't look too bad once the wipers have been put back on.
I took the car to a local Autoglass today (not raining for a change) to do a free survey on the condition of my windscreen and to take the opportunity to get their opinion on the seal. Like you they said "The grill has been subjected to 15 years of summer and winter and has probably distorted slightly. There is no need to use sealant to fill gaps because the car is designed to allow any water ingress below the grill to pass through drain holes and on to the road below. The seal is primarily for cosmetic purpose, as are the seals at the top and sides of the windscreen."
If you think about it, even if the seal was stuck to the windscreen water would still get in through:
1. The gap where the two grills join together
2. The gap around the splined shafts for the wipers
I shall make it part of my annual maintenance to ensure the drain holes are kept clear, especially after the amount of dirt and leaves I've just dug out.
