I have about 3 very good used deco type collectors bringing some designs I have not seen too often. They get the stuff for a song, from all over, don't ask me how. They are just shrewd business women. The scratch repair is not perfect, but we can make it about 80% better visually. There is always haze, it is never like it was fresh from the sheet manufacturer.
The viewing angle is important. Only till we put this in the car, did we see more scratches.
