HI I have with my Audi A4 B5 laser red after a day polish scratcher on the car????? I don’t understand where I polished it with Sonax everything was top! neither on the trunk nor scratcher as on the door! then it rained in the evening… now come always and more scratcher to appear????? I don’t know why;______________; now my question, can it be made visible by the polished old scratcher….so that through the rain then everything went off? would answer me over very happy……. only I didn’t see them all before!!! the go crooked and crosswise and then…….as if you were to push a nail in so round scratcher…. and just finger long… very funny…… achso give me a pen at a.t.u where you can paint over with the scratcher? have seen such a thing in tv… would be very happy to answer….
