Hey all doing a valve adjustment on a 2rz and had to purchase a couple new shims to get it sorted. Upon reception of the shims they appear to have a dull protective coating on them (maybe corrosion protection) and are not mirror finished like the ones that I'm swapping them with. My assumption is to remove this finish? Or is it ready for install as is?? If it needs to be removed what do I use?? Thanks again in advance for the help!
