Topic: 1940 Ford Master Cylinder

  Is it a good idea to paint the external surface of a new master cylinder to prevent rust from forming? I thought a good grade of oil based black would be a good protectant. I realize this is not a factory original practice.

  Any spilled brake fluid would likely deteriorate the paint.

  I would prime it and paint it. Then just do not over fill

  I use Eastwood's "cast iron" paint. It allows for a protective finish and is a decent approximation of "fresh" cast iron.

  I think the Model A guys use model airplane paint on their carbs. This is the paint that keeps the paint from dissolving when the fuel from the airplane engine gets on it. You might check that out.

  I've used the clear POR-15 over the natural cast iron finish on my master cylinders. Seems to hold up good.
