I want to chime in that I bought some Meguiar's Quick Detailing stuff, which I assume is the same stuff but $10 more a bottle, and I can't tell a difference.
Ok, I finally tried it today. I only did the back hatch, but overall it looks good. No scratches and it's nice and shiny. That's my hubby's 2006 Cobalt SS in the background getting a new header, down pipe and cat back today.
Email Sent, Looking forward to giving this a shot
