My car wasn't new so I didn't have the option to get it done with perfect paint, but I finally got around to putting Opti Gloss on my 38,000km car yesterday. Looks pretty good, I know its not perfect, but it looks a lot better than it did, and the feel now is really glossy and slick. Bugs seem to come off a lot easier too. I put it everywhere on the exterior and even did the windshield too, to hopefully help against stone chips.
