I was looking at my black dash the other day and noticed it had a very light gray tinge to it. After looking really close at it i realized that it was from overspray . I had painted my truck 4 years ago , now this overspray has been baked into the vinyl dash pad by the hot summer sun over this period of time. This is not a show truck but is instead a mud truck, therefore I never give it much thought before. What (if any) would be the best way to remove this haze without damaging the vinyl.
