It's not that hard to do. I did my toolbox in the blue marbilizer. It looked awesome. They take the basecoat which is black. They spray that down. Then they spray the marbilizer in the color that you want. Red, blue, yellow, pink, green, Orange. Then as soon as you spray the marbilizer you take saran wrap and lightly spread on it to get that look to it. Wait 2 minutes and pull saran wrap off. Then spray you clear coat. Its pretty Cool when its done. Also I have done this too is when you paint your stripes I've taken a torch and lite just the acetalyn bottle and let the black soote fall down on the paint and then clear coat over that. People would ask how I did it. Also you can do water droplets to. Spray your paint. Then take water bottle and spray droplets of water on the paint. Let it dry and the spray clear over it. Just a few options I have done in the past.
