I don't like using the vinyl so was thinking of spraying the tint on then laquring by a pro-bodyshop. I did the same thing on my Audi TT and they came out good. Like you I agree that a darker tint on a white Tig looks much better than standard.
I'd be interested to see what you decide for the front badge. They come off easily (too easily for my liking) so you can chop and change the look quickly.
