Re: inside the lens ?
Did mine on my 04', but never trust a quick fix, so did them by wet-sanding, then compound. Came up like new. sand complete with 320 first and make sure any shiny spots are gone. Then work your way up, 500,1000, 1500 or 2000 and then buff with medium compound, followed by scratch/swirl remover or baking soda. You can then spray a coat or 2 of Clearcoat for extra protection, or at very least, a good old coat of wax.
