Black Razor this finish is just mean. It changes from Black to Purple and every color in between “murdered out” or all black flatstick. For others, the black Razor backdrop is ideal for limitless options in terms of paint fill, stamping and personalization. NorCal has several different matte finishes depending on your texture preference. As for paint fill, good luck finding something that doesn’t look good on this finish. I love the way it looks with black paint fills.This finish can be applied to carbon or stainless steel as well as aluminum.
