It doesn't protect against stones, checkout their website:Ridgemanron said:there's a product sold on the 'left coast'
called Crystal Guard. The Ferrari, Porsche
and Nizzan Z owners are swearing by it.
Not a wax, but applied easily like one.
protect against stones, and the like, and
looks like the product of the future..now!
I must be missing something. Nowhere on their site can I find where they claim it protects against stones chips.Ridgemanron said:Re: Crystal Guard literature- "Crystal guard is 800% more durable than the typical Teflon-based polymer coating."
That's an Absolute Hardness Rating of
72. Iron nails are a 21, while other sealants are only a 9. You get great resistance to stones being tossed up at your car when you realize even with momentum, they might reach 3 times
that of an iron nail (62). That is still under
Crystal Guard's protection (hardness) level of 72.
