Has anyone Re grain there car I have read of people using 80 grit sand paper. I my self have cleaned my car with a 3M sanding like sponge that you would find in Walmart medium to corse and it does bring a great glow to it. But I find it hard to run the sponge correctly along the fenders to give it a correct grain look. Has anyone master this technic. Any suggestion would be appriciated. I have also read about a sanding disk made of made of some sort of fiber brizzles bought at our local Lowes lumber store, Any one use this technic. Thanks Hugo Vin 2800
