I use Novus products.
They have 3 levels of cleaning/buffing removing scratches etc. products. However, they will not "fix" damage.

Piano black polish and refinish
Is there a kit or a very good tutorial for the "normal man" to fix/repair/refinish piano black speakers? I figured surely there's a good kit with the right compounds and etc made for pianos but the only real advice I've seen is a complete rebuild or taking it to a car paint shop.
