Never Dull. :yes2: Used it in band to clean the brass instruments, works great on chrome on the motorcycle, cleaned the bells at church, use on a brass penny and it looks like new. Cheap, easy to find and goes a long way.
For crying out loud the paint has failed.
Take it to an auto body shop and see how much they will charge to paint then pinstripe the edges and numbers.Some times there isn't a chemical solution to a problem.
