I got rid of them by using the misses hair drier, on a cool setting and constantly checking the plastic wasnt over heating by touching it, then placed the heaviest and biggest books I could find evenly over the affected area. then left it to cool and repeated as necissary. This worked great. there were still some small wrinkles but I decided not to risk over heating the window and let the sun do the rest when it was stretched on the car.

Im certain I took better pics of it than this but damned if I can find them. Above you can see one of the books in use and the next step before installing which is the double sided seal between the sides and the body. Again, couldn't or didn't find the original gear but a sutable alternative is licence plate adhesive. same thickness same water proofing same double sided stickyness lots cheaper.
