I think tbh its just the front material that is casing the adhesion issues ,ive used stuck on plates for years but not even gonna try any more with this car, the rear is ok but the front no.I think @Number1Plates are having email problems. They are usually quite responsive via FB messenger if you're on there.
I've had no problems with Scotch number plate pads - even with curves. Not a fan of screws either.

as for number 1 plates i will give them until monday to reply ,i really hate dealing with a company i cannot pick up a phone and speak to. a bit disappointed to be honest, and the plates they sent do not have the correct bsau 145e stamp ,they did say they would replace them to be fair .
