I did my truck and entire 5th wheel trailer with Mothers CMX. Very impressed. First time I've used a ceramic. Pretty much spray on, wipe off. Needs 24 hour curing time between coats.
* there is a unique smell when applying (nothing like wax). But I doubt it would linger at all. I've done a few watches with it (metal case and crystal) as well and excellent results. 5 coats over the course of a week.
