Could try hot and cold to slightly stretch it. Fit to windscreen, secure problem press stud with lightly tensioned cramp, use hairdryer to heat area between it and next stud till it feels a bit soft and pliable then pour or spray on cold water, this has worked for me before in an upholstery situation when working with vinyl/faux leather. May be worth a try Pete before spending time and money. (don't use heat gun/paint stripper you could crack glass). Bill.
