Dont wrap the mirrors, especially if your thinking of the carbon fibre effect wrap.. Waste of money and will shrink, as its stretched to install.
Been there twice with Racoon Vehical wraps many moons ago...
This wrap is good as long as its not stretched to apply.
Mirrors will looked better resprayed, or buy a spare set and keep the origonals.
Ive since opted for Black gloss wrap on various parts on my car, and as i said, as long as its not stretched on, it will hold with no issue as long as its to a pre painted surface, and not over plastic.
