If you have aluminum transfer then get the aluminum off. Ive used oil and fine emery to remove it very successfully. It takes time. The chrome is very thin. Its hard but thin. If you google honing a chrome cylinder there are several discussions about it and a few from this site back 10yrs ago. Some say never do it others say go for it. Seems theres no right answer. If i had a hone and it seemed warranted id try it. Id be cautious though.Should I hone the cylinder or just use sand paper? Mcculloch 7-10 chrome bore
