I have heard of people doing this to make the oil drain back down to
the sump faster. The theory is that oil runs down smooth shiny paint
faster than bare cast iron. If you buy this theory, a better (read
"more expensive") method might be to use a grinder to smooth the walls
so you don't run the risk of paint flaking off the inside....
