I used clear packing tape on my type cover 2. It is amazing how much better the track pad works with this smooth surface. The taps and movement are just as sensitive if not more so with the tape on it. This is the tape that sticks to everything as you are trying to wrap a package. But on the type cover fuzz, it does adhere but peels off easily.
I cut a three inch piece of the tape and stuck it on the non-stick side of Reynolds non-stick foil. That allowed me to cut it with scissors to match the outline of the track pad. The,n I used an xacto knife to pick at the corner of the foil to separate it from the tape, stuck the tape in place on one edge of the track pad and pulled the foil off as I stuck the tape on.
The final touch was to use a credit card to smooth and press down the tape on the type cover fuzz and then I outlined the track pad with a black Sharpie.
The smooth finish makes all the difference in the world in using this keyboard.
