I have a black SX top case that I bought earlier, but it has since been faded to a grayish color. Any suggestion on what I can do to make it "blacker"? spray paint or something?

I havent tried it but I have heard from others that back to black works very well. You may want to try it before painting. If you do, let us know how well it works! http://www.superiorcarcare.net/mobatrca.html

If it's the fabric type canvas topcase then don't use back to black, you probably shouldn't use it on painted or plastic surfaces either. Get a spray upholstery dye like the one on this page

If it's plastic use a good quality polish and see if it helps if not, then it's time for spray paint.
