What effect are you referring to? Im guna be shocked if it holds up for any length of time to be honest with ya. I already have aircraft coating remover, just in case. haha
I did this just out of curiosity really. If the Black shadow is applied over a real chrome or "real chrome", it would probably have the proper effect. But when applied over spray chrome, it mainly turns gunmetal. So I went to town on the sides of the pipe in order to highlight the top portions of the piping. I had to fix up the large intake pipe, and ran low on paint, so its a tad blochy. I do still think that the finish is really cool. In the sunlight, it almost has a blue/green color to it. Its not black to grey. It looks really cool.
