After three years of trouble free PPF on the front and bonnet I managed to get a bubble of water under the PPF through an unseen stone chip right on top of the bonnet. What's the best technique for teasing it out back to flat? I can live with the little chip if I can get out what's underneath. It looks like the area close to the chip is back down but there is water further away that I can't easily push to the chip. Any expert suggestions? I may go to a PPF bloke but perhaps it's something I can do.
