Rusty edge in washer

<!-- SC_OFF --><div class="md"><p>Under the lip inside of a tenant washer the enamel is gone and the edge is rusty. But the machine still works. I&#39;d like to file off the rust and put a new coating on and see if I can buy another year or two out of the machine.</p> <p>Suggestions on a paint or paint like product?</p> </div><!-- SC_ON --> submitted by
