These two products seem very similar. Has anyone used both? Which protects better? Which shines better?

I'm intending to use either product for all hard surfaces - paint, glass, and wheels.

 

...and how/where do you buy CrystalGuard??? I tried calling their phone #, but it just rings endlessly. The cell phone goes straight to voicemail. The online store weblink goes to a page with dead links when I click on the product. Arrrrgh!

They sure make it hard for customers to buy their product!

 

I finally found the contact person who is taking care for the Crystal Guard stuff. She told me that the Website is down for repair (something relates to my350z.com). You can email her at info@CrystalGuard.com. She can process the order for you. I got mine today. Hope it helps!
