IMO...Good read. An entirely unbiased point of view?...but, nothing personal (I appreciate being updated on anything car care), thanks for sharing this article Megan.
Just for discussion sake:
I was under the impression that most modern auto paint's top finishes were of a clear nature, that is an alleged unpigmented clear-coat. If one adds pigmented wax,(1,2,6, or more layers) to the clear-coat paint the effect on this unpigmented clear would then surely be "unnatural", occluded, or otherwise obscured. As it has pointed out that wax just "sits" on top of the clear-coat, these effects, however 'subtle' to the
"eye of the beholder" would, it seems, become more "unnatural" as the pigmented wax starts to fail/diminish/streak/wear away. IMO...Same analogy goes for most waxes.
That is why, unless otherwise requested, I now use LSPs that, IMO, imparts the most clear/shiniest/mirror-like results I can find (sealants, coatings).
Just my dollar two ninety-eight.
