What looks wicked is an Oakley sticker over the front rear view mirror mounting point or centred at the top of the back window. "Factory Pilot" or "Thermonuclear Protection" (or maybe a hybrid of the 2) was the go I think. Everyone had of these in the late 80's/early 90's and everyone looked cool.
Ive had the odd red one when I was a lad Have never put surf brand stickers on any of my cars tho. Not that I didnt want to, just never thought to do it. Not going to start now tho.
