Layering

Just waxed my car with White Wax.
I like to apply a 2nd coat and I have 2 choices: White Wax or Ultimate Paste Wax.
Out of the 2 waxes, which one would you use?

White Wax is no longer produced but was / still is a great product with the extra cleaning ability really helps for light colored vehicles. If you apply White Wax again, you will have spent that much more time utilizing the cleaning ability if you feel the paint needs it. If you apply Ultimate, this has no cleaning ability but will leave you with better protection.

Thanks, Nick. I should have guessed that White Wax is a cleaner wax.

Also, I found a can of Mirror Glaze Professional Paste Wax M16 with some product left. The wax looks OK, not watery and still in paste form. There maybe enough product to do my car (Civic Coupe SI). How about I use up this 16 wax first?

I recall I had some old NXT and it would turn watery after a few years. How about M16? This wax is even older, while the wax still looks good, how can I tell if it is still effective?

In its day before VOC regulations, M16 was legendary to deliver best-in-class durability and shine. Not sure how it compares to ULW.
