How hard is your paint? Some years ago I was pulling the hair out of my head until there was none. So I came here to get an answer and received lot of the information almost all did not help. I remember saying that even a cotton ball would scratch and it got to the point from chasing the fine scratches, that very faintly red primer was starting to show. Accumulator made a great suggestion. Buy some Opti-coat. The coating was a another level of clear that was harder than the factory paint and my problem was solved. The primer was almost impossible to see unless you knew where to look. Now the Audi was the opposite situation and since then I`ve gained an appreciation for hard paint.
