Ask Bob: Extending Muffler Life
by Bob DeP.
I just recently replaced the muffler on my 1988 Mercury Topaz. I live in the Northeast. I bought the cheaper version of the muffler. Is it safe to paint my new muffler with heat-resistant, rust-proof paint, to possibly extend its life and protect it from rusting out due to the elements?
Painting the outside of the muffler will do nothing but make it look pretty. Mufflers rust from the inside out, not outside in. One of the components in exhaust, when mixed with water, becomes acid. It is this acid that destroys mufflers.
