I will be replacing the sheet metal shell of my 3 bolt 1915 muffler with cast iron ends. Before I reassemble the muffler, I thought I would clean up the cast iron ends. My question is, were the cast iron ends left as raw cast iron when new, or were they painted black, like the engine was?
Ford alternated during this time painting the muffler and its asbestos wrapping, or not. If you paint it the paint quickly burns off. I guess that you could have it ceramic coated if you wanted it to be shiny black. I am used to seeing them with a coating of surface rust. Looks fine to me.
I painted the ends of the muffler on my 16 after grit blasting and cleaning. So far the paint is still on the ends. I used VHT high temp frame paint.
Does the muffler need regular cleaning? I wondered if it gets accumulated with dry exhaust stuff that could cause back pressure?
Marty... No, it should never need to be taken apart to clean out carbon deposits. But it may need to be taken apart and cleaned out if mice build a nest in it.
Todd, Thanks. That's going to save me some work!
