NXT Metal Polysh vs NXT Wax

[mis3]

My wheels are in good conditions. I have been using NXT Paste Wax, sometimes Wheel Wax to clean and protect them.

Now, I just bought NXT Metal Polysh. My question is in term of protection, which product is better?

Winter is coming. I will not be cleaning my car as much. Which product would give me better durability to protect against road salt and snow? I have dedicated winter wheels (Mercedes stock wheels).

Iwould say Nxt Metal polish first. Then, if you want to be sure, you could top with Nxt.
