Just to update you guys - I did end up finding some lapping compound from a motorcycle shop - I couldn't get it at Canadian Tire and I didn't want to wait for Amazon. I lap-ground the one valve that had black scoring on the inner drum which took away most of the tarnish. Cleaning out the lapping compound from the outer valve assembly was a pain. I wiped, washed with a wet rag and dish soap, then re-assembled with grease, then found it still "gritty" when I operated the valve, so I dismantled it again, wiped clean again, re-greased and re-assembled. It still feels a little "gritty" but I think it's just the two newly sanded/ground surfaces rubbing together. Everything is greased up and re-assembled and I splash on Monday. Wish me luck!!
