Crystal Guard

very strong marketing claims, yet they try and remain sane about it.



I'm very curious about this product, and hope someone does a review of it soon. I just blew all my funds for car care products for the next six months, so I can't do it!



Anyone have an opinion on this product?

Don't take it wrong!

Many people say "If you claim a hardness of 6 then key your car. It shouldn't get scratched with that, right?!!" The answer to this question is "It could be scratched." CrystalGuard has a hardness of approximately 6, however, it's only 0.5 to a few microns thick and can not protect against intentional scratches and strong impacts. You can add strength by adding more layers but still it is only a few microns thick. Large impact such as a big rock hit may be able to break the layer. Even with natural dust, some % of those are harder than a hardness 6, and may scratch the CrystalGuard layer if you wipe the body with a towel without washing. However, CrystalGuard is still much stronger than other sealant products. It minimizes the possibilities of scratches and maximizes protection for the entire body of the car dramatically.

Interesting Claim. I don't totally doubt they can make a synthetic protectent that gets extremely hard. I'm atleast glad they tell you how thin the coats of wax is and don't go making some totally unreal claim of "prevent all scratches."
 
The whole hardness claim is out of whack. They use Moh's hardness scale for minerals (I am a geologist by schooling), so that stuff should be as hard as glass. A simple test would be to use your fingernail to try to scratch it. 7 is harder than glass. As a matter of fact, 7 is the hardness of Si02, which is crystalline silica. So you should be able to take a piece of glass and rake it over the paint and not get scratches.



Up to that point, they had me interested. After that, forget it.:down

Click to expand...



Well, if I get some of it and someone lets me use their car, then I'll apply it and rake glass over it.



So, anyone have a car I can use?
 
Hmmmmm........... 8 times tougher than other polymer sealants? I don't know, I guess I still subscribe to the theory "If it sounds to good to be true, it probably is!". Then again, I've been wrong before! :D
 
If it's so hard, is it less flexible? :nixweiss



One of the more technical debates about synthetic vs. carnauba waxes involves talking about how synthetics can be made flexible so they expand and shrink with the paint rather than just crack and fissure (supposedly like carnauba wax does). I have trouble seeing how it can be both hard and pliable.
