I started working again on the Treadlevac long after it was disassembled and partially cleaned. There was an issue with the replacement reproduction master cylinder that had to be resolved which took considerable time but I finally got fixed so now it's ready to continue. Of course, the original cylinder could have been used but it's rough inside and had a tiny thin spot at the edge where the cover has to seal so I didn't want to risk it.

Since there was a bit of surface rust on the outside of the booster housing, I started treating it with a rust remover that seems to be doing the trick nicely. After honing the booster, though, there are a couple spots that won't come out. Should I be concerned or are they close enough to the edge to be away from the piston?

Another question, is the booster cover supposed to be painted black or was it zinc plated originally?
