First thing I removed the base, here it is sitting on top of the carbon fibre vinyl.
I didn't need to cover the whole base so I just cut out enough vinyl to wrap around the edges.
The vinyl just sticks onto the plastic.
I used a hair dryer to help mould the vinyl around the base as I wrapped it around.
Eventually I had all the surface around the base covered.
Putting the case back together, it looks quite impressive.
I thought about covering the rest of the case in green carbon fibre vinyl, but I'm not sure how good that would look.
