I still have 4 tins of this wax. It is a pure wax with no cleaners so it perform great as a topper for sealants. It doesn't darken colors like many carnaubas do. It easily lasts 3+ months so it is very durable, right up there with 476 IMO. It needs to be applied very thinly or removal may be difficult. I get about 80 applications per tin so it is quite economical.
I always use #16 as a winter topper over a sealant which easily handles the winter's worst 4-5 months of snow and salt.
I love to hand apply this product. Maybe it's just because I'm old school but this wax smells like crayons and applies so easily that it feels like therapy for me. The wax has a highly reflective shine. As I mentioned earlier, if you're looking for a warm carnauba glow this is not going to provide that look. It is more like a sealant in that it imparts a steely, high gloss shine. It also is one of the best waxes at producing tiny and very high water beads in the rain.
This product has been around unchanged for a very, very long time, until the CCAB and EPA decided that it's VOC's were too high. I believe I was around 15 YO when I first used #16. I'm now 65. I've always considered this one of
Meguiar's best carnauba products through the years.
