Why do we use spray test panel cards before we spray chrome for customers?

We use spray test panel cards every time we start a new batch of spray Chromed items. 

This is to check that the chrome is chemically reacting the way it should.  This also is to make sure the Chrome spray is up to our high standards that we pride ourselves with here at Chromefinish.

Once we know the spray cards are as they should be, this means we can then start work on the customers items, knowing that the Chrome will work its magic!
