I have recently had my windscreen replaced due to large deep scratch going across my line of vision. After it had been replaced I came to clean the car and noticed the black spots of window primer on the front of the car. They came back on saturday to have a go with their "special" chemicals for removing primer, which turned out to just be Tcut colour restorer. I then had to email the branch manager and he agrees it looks like primer and is going to call me back by the end of tomrrow. Have you guys got any ideas on how to get it off as I would rather not go down having the bumper sprayed if I don't need to.
