A friend of mine was recommended to use this on her new black BMW 325i. I'd never heard of it. Can anyone help out? Thanks.

 

I use Zymol. Not the phony stuff that's made in Chicago by Turtle Wax, but the real stuff that's made in Connecticut. Their Japon wax is terrific! One 8-ounce jar and you can use it to wax your car 10-20 times. Apply their HD-Cleanse beforehand to remove any oxidation or surface contaminants.

You can find out where to get Zymol in your area by clicking here, or you can order it from their website or from Emmons Coachworks.
