Hi great advice I never thought of dome chemical being used And the scratches are quite deep and in random patterns which led me to believe that some one was up to no good, I'm just waiting on a webcam with inferred which will point down on my drive.
I have thought about spraying the car myself only thing Is previous owner had it sprayed a different colour it used to be silver according to paint code.
As for the damage it looks like they used a razor blade or something because a key and a knife like you said won't cause damage like that if you zoom in you can see the marks go all sorts of directions.
Unless the paint job was crap to begin with and maybe old marks are starting to show through paint but I highly doubt it
