I bought some PPF off Amazon and cut it myself. I bet it cost me over $10 so precut for $17 sounds like a good way to go. By the way, I have been using mine since getting the CT in May and it has been great.
I didn't bother with any ppf and after the first wash, my truck stays pretty fingerprint free. Having said that, I DID buy the center caps from Abstract Ocean and if their PPF delivery is anywhere near as well done as that delivery, I'd say you can order with confindence.
