Protection: Carnauba or Synthetic.

[supercharged]

I have to say,you won't be disappointed with 476.The beading quality of this wax is incredible.I can't comment on durability because its the first time I have personally used it.It gives a deep gloss to red paint.Two thumbs up.

I haven't tested durability on 476 yet, but I think it will last just as long as #16, or even longer. Expect a full winter protection with 2 coats of it. (4 months+ through winter, 6 months+ through summer).
476 is simply a nice product.
