I don't want to sound like a dumbass, but do you think its possible to polish the cover while its still on the engine? I know it would be more of a pain because of having to work around it instead of moving it whenever needed. but I've drained and refilled my engine so many times in the past month its starting to get old. But if I have to take it off I'll wait a little while to polish it. Thanks a lot for the advice!
