I used Serpine on my ‘57 Thunderbird this summer: wow! It’s really astonishing how good this wax is. If you’re looking for a wet reflective look, it doesn’t get any better than Serpine! The attached pictures give an idea of the results with Serpine, but they don’t fully do it justice; you have to see Serpine in person to really get it.
I have several other M&K waxes and like them all. I’ll continue to use others, such as Lily, when I want a different look; but when I want “wet and reflective,” Serpine will be my go-to wax.
