Having had a good friend back in MI who owns a body shop for high end cars. He told me those paints are impossible to blend for small scratches or dents and at a minimum you have to paint a complete panel. Even at that, a good eye will see the difference as there is no real way to mix the exact same formula all the time. So word of caution, also, watch your insurance rates!!! Some will charge extra if you select those paints as a simple paint job or repair could cost in the thousands and they know it!
