The bottom line is that Griots 3 in 1 ceramic lasts as long as the very best products available, and is silly easy to use. It also provides a stunning gloss. A number of tests show it outperforming top names over a long period of time. I use it on everything. Again, quite simply it's so easy, and the results are so good, why use anything else? Interestingly, it also provides excellent brake dust protection on wheels.
The only product that I've found with possibly a deeper gloss is Griots "best in show" wax. However, that product does not last as long, nor is it as easy.
There are plenty of foo-foo products out there. I've not found one of them able to match this:
Hint: this guy puts gasoline, automatic transmission fluid and just about every cleaner available on the panel before it starts to weaken. Even then the gloss is higher than when he started!
