-3M Di-Noc CA-421 carbon fiber vinyl (there are other styles available, including different shades of carbon fiber. CA-421 corresponds to the traditional black-and-grey-ish carbon fiber look)
-X-acto knife or razor blade
-Plastic card for smoothing out bubbles (an old credit card will work, but it helps to smooth the edges a little)
-Heat gun (hair dryer will work, but an adjustable heat gun is preferred)
I found everything I needed except the vinyl at the TechShop in Menlo Park, CA. Check out their website, http://www.techshop.ws, if you're interested. TechShop is a membership-based workshop that provides members with access to tools and equipment, instruction, and a community of creative and supportive people so they can build the things they have always wanted to make.
