a guy did on comparing different waxes/sealants, not sure if it was on this forum, but seems like it was. Seems like it was on a red hood, he had his neighbors come compare doing blind comparisons and longevity reports on each product he tested. I think I marked it on my old laptop, which is no longer with me, and I can't seem to find it now.

Any help is appreciated. I've searched here, and on a number of other forums I'm familiar with that discuss detailing with no luck yet.
