-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.
Step 1: Step 1: Measure trim
Step 2: Step 2: Remove trim
Step 3: Step 3: Applying the vinyl
Once you've got the initial alignment done, you can start working it around the rest of the flat surfaces until you get to the corners. Anytime you need to wrap around a corner or irregularity, you'll need to break out the heat gun. The vinyl responds very well to heat, so be careful and don't get it to hot because it will melt if you do.
To wrap around contours, heat the vinyl a little until it is soft, then work it around with a plastic card, making sure to clear any air bubbles that you get and avoid any wrinkles. Once you have reached the edge of the trim, you can trim the vinyl down to size, leaving about a quarter inch to wrap around the back side.
It helps at this point to notch the corners of the vinyl where the trim has a sharp external corner, and put a few slits in it anywhere the trim has a round internal corner, as pictured.
Make sure to use the heat gun when you fold the vinyl over to the backside, and it should hold extremely well once it cools.
Step 4: Step 4: Reinstall trim
Now step back and admire your work!
