Note that technically you can use approximately any flat thin nonconductive thing in the right shape as a touchwheel cover. IIRC there were originally plans to use glass that didn't pan out for some reason, and the FR4 ones we got were the backup plan.
It'll probably work fine without a cover too, but if you're using it hard enough to need to replace the stock touchwheel cover, you'll probably also damage the solder mask behind it at some point.
I am at least partially wrong, see below.
