Zinc chloride.
Light grey.
Place a zinc strip in a clean test tube and add dilute hydrochloric acid. The strip dissolves and the result is a colorless solution. The products are zinc chloride and gaseous hydrogen.

No, it is not. Since zinc is highly reactive, therefore it will react with copper sulphate to form zinc sulphate and deposit copper.
Zinc is higher than copper in the electrochemical series, so it will displace copper from it's solutions.Zn + CuSO4 = ZnSO4 + CuCopper plates onto the zinc as a small amount of zinc sulphate is produced.
Potassium will surround the Zn So it's name will be ZnCl2
A grey deposit slowly forms on the surface of the zinc. I think it's zinc chloride + platinum?
Silvery grey.

This will have to be sanded off. After the oxidation has been removed the strip should be sealed with a sealer.
