Picked up this can today at Lowe's for about $4.25 and it works great on the CVX. I've used the liquid form for over 13 years in my home on the cultured marble and chrome faucets. I'm pretty good about applying some to the tub surround, vanity and faucets about every quarter. After 13 years I don't have any water spots and the areas still look new.
Spray it on, wipe it around and then take it off. Super slick.
Give it a try.
