This coating sounds like Glyptol, which is that color. It is used as
electrical insulating varnish for electric motors, generators, etc..
It has also become a popular product to paint the inside of motors, gear
cases, and oil pans. The benefits are that is slick when cured and allows
the oil to flow easily. It is very impervious to oil and gasoline and heat.
If applied to a clean, degreased surface, it generally last a long time. I
recently bought a quart in AutoZone for my engine rebuild. It is also sold
by Eastwood, and some others. I think it is available in spray cans as well
.
