My interior walls are pretty beat up and I just got a tire cover that was faded. We used the plastic spray paint that does not require primer and can be found at home depot. It def is more black and has more of a sheen compared to stock but I'm very impressed with the easy application and instant, new car looking results. If it holds up, we will do everything except the dash. I'll post pics when I figure out how from my phone. Anybody else used this product?
