I`d be amiss for not chiming in on Collinite Waxes. I, too, learned of this wax from this forum. (Remember when 476S and 845 wax somehow ended up for sale at Harbor Freights for cheap!?). I found out it really is a great boat wax, and I bought a large tin of 885 Fleet Wax at a local marine supply shop, being the marine identical twin to 476S Double Detergent-proof Wax. I`ve used 885 on a wide variety of daily drivers that I have done for friends and family with great results from vehicle owners.
I was finally able to purchase 915 Marque `d Elegance wax from Detailed Image, thinking it would be a step up from 467S. It is on dark-colored cars, as many of you have found out. I`ve used it because it was relatively "inexpensive" (AKA cost-effective) for a "high-end" wax that offered longevity. My only other "high-end wax" was AutoGlym`s High-Definition Wax that I, like most Autopians here, purchased at Walmart on close-out when the line of AG products was being discontinued/dropped. I like 915 a little "better" because I find it`s a wax-on-wax-off application. I know some of you prefer to let it set up, but I think that is part of the problem of removal difficulties. That, and using too much, which I do because I am a "wax waister" with a more-is-better mentality.
Needless to say, I highly recommend 915 as an LSP to anyone who has a dark-colored vehicle that they drive on a regular basis. It`s great carnauba looks combined with some degree of longevity and protection and at a reasonable cost for a "high-end" wax is why I give it the recommendation to add it to anyone`s LSP collection.
One other aspect of this wax is the insane water beading. While this is a highly subjective characteristic of an LSP`s protective ability (and it is in my eyes), it does offer the benefit of easy water remover when blow-drying a vehicle after a 2-bucket wash. I think Dave Fermani pointed this out many years ago about carnauba-based waxes having this unique characteristic and how it lends/aids itself in the blow drying of a vehicle because the water droplets (beads) just roll off with ease due to the reduced surface tension. It is one of the reasons I prefer to use a carnauba wax as an LSP for that characteristic in my wash-n-dry regiment.
