FYI - Subaru sells BRZ fender garnishes pre-painted. When I was looking for mine, the local Subaru parts department told me they did not. I bought some unpainted ones and had them painted (which came out poorly) and then ended up buying a used set for too much $$$.
You can get a brand new set for like $140 painted here:
