I've been told NuFinish is total snake oil, and as likely to harm your finish as help it. Take that with a grain of salt, I've not read nor heard that anyplace I necessarily trust.
I use Zaino Bros Z.1 and Z.2 on my Bullitt. Everyone seems to say it's so much work. I don't see it as being any more than any other wax/polish. You wipe it on, wait for it to glaze, then buff the crap out of it with some elbow grease. Isn't this the same with any wax/polish? Speaking of which, someone here mentioned that detailing sprays which contain wax may not get along well with Zaino Bros products. (none of which are wax-based) I don't have the specifics on which ones to worry about. The instructions say Z.1 is only needed once or twice a year. They suggest that multiple coats of Z.2 have progressively deeper/shinier/wetter look, though this may be typical marketing hype. I haven't tried it yet. However, 1 coat of Z.1/Z.2 had my car looking better than the day I picked it up, by FAR. I'd love the chance to give a couple of back to back coats and see what things look like. I can honestly say that I've never seen such a big before/after difference on any car when I've waxed it.
I use Blue Coral leather cleaner and leather conditioner (two separate products) on the interior, and I've been happy with it, though the conditioner leaves a fairly matte haze over the leather which I don't necessarily love.
I use Zaino Bros tire dressing, which, as advertised, is not nearly as shiny as silicone dressings. I like it quite a bit.
I'd be interested to hear people's storied with different detailing sprays, too. Plus brake dust inhibitor/cleaner. I heard someone say "don't brake as hard" on some other board, and thought they must be kidding! :smile:
