Hello all. I would like to wrap my car in 3m vinyl but I had some concerns. My car is an 04 with normal road wear that the car has accumulated through the years. With that, there are minor rock chips in the paint and a couple of scratches that catch my fingernail. I would ideally like to somehow fill them in so that my wrap will be uniform in appearance. What is the best approach to this? I was thinking of using a spot putty to fill in but is that ideal? I have tried to use factory paint and 1500 grit to slowly fill with crappy results. I also have a couple of minor dents from a hailstorm last year. If I were to sand the paint down to metal and use bondo, would I absolutely have to apply primer seeing that I will be applying vinyl shortly after the bondo has cured? Thanks for any help.
