Platinum looks solid white while high shine is just silver. Eventually, the back (top) of the high shine loses the shiny silver colour and goes back to that greyish colour we see on regular silvers. If you look at the pic Don just posted compared to one of the bigger pics A.Importz posted, you can see the difference in colour on the aro's back. The plat is completely white while the high shine isn't.Juxtaroberto;4669629; said:How can you tell the difference between platinum and high shine? They honestly look the same to me...
