Query: older yes newer no

I really like the shape and that it's not glass . BUT SALT AIR MAKES THE SURFACE PIT i wax once a month . I buy one every year for the last 5 years .[ i'm a glutton for punishment] about 6 years ago i bought one for a friend of mine' and with no pitting at all , and very little maintance it still looks brand new.this tells me that the older mirrors had thicker plateing . go back to heavier plateing i'll pay the extra money. zirmack and salt don't mix RON
