Can silver gel and Silver Star be used on silver?

Our products for electroless silver plating only deposit on copper and brass as a base, as the products can only deposit silver with these materials. Accordingly, the products for electroless silver plating can NOT be deposited on silver. If copper or brass are coated, a thin silver layer of 200 - 300 nm is produced, which is intended for decorative purposes only. If you want a thicker silver layer on your object, the only process left is electroplating!
