SilverLexus said:I'm still skeptical. Guru Reports tested Collinite Marque D'Elegance and it started crapping out in eight weeks.
I don't consider Guru Reports to be the authority on waxes and sealants. #26 lasted the full 8 weeks and they blew that score, giving durability a C when all the other waxes that lasted 8 weeks got B or B+. Static panels aren't real world testing anyway.
I get 5+ months with #16 on a regular customer's Expidition and I wash it conventionally. Very typical results with #16 for me and apparently, a lot of other people. Plus, it has been my experience that carnaubas are more resistant to bird bombs than sealants are. Maybe carnaubas leave a thicker barrier. :nixweiss
