Pulling the old seals off leaves a strip of the self adhesive material firmly stuck to each inner edge of windscreen pillar. This is extremely difficult to remove until I discovered this method:
Soften remaining material with brake cleaner then start peeling from edge with finger nail. Once started continue with downward thumb pressure. The material should peel off cleanly rolling into a ball which can be picked off when large enough. Clean any residue with paper towel soaked in brake cleaner. This leaves clean surface ready to accept new seals.
