Just waxed my Camry with Prestone yesterday, resulted in a really nice shine.
A few things about the CR report I neglected to mention;
They tested mostly OTC waxes, I think the cheap version of Zymol was the most expensive wax tested.
This test took place around 4 years ago, I don't think Mother's Reflections, Meguiars' NXT or Eagles Nanowax were on the market yet. IOW, I don't think CR tested any of the new, inexpensive synthetic waxes.
They rated Prestone highly for looks and it was also the most durable (IIRC) of any wax in the test. The test did include many popular waxes such as Mothers Original Carnuba and Meguiars Cleaner/Wax.
Anyway, just wanted to pass on that info. I have a subscription to the CR website, but the report doesn't seem to be online. I really like the Prestone wax. Very, very easy to apply and remove, doesn't leave behind any residue, and doesn't stain trim at all.
My only concern is the percentage of Petroleum Distillates they use. I'm not certain how much is in the wax, I emailed Prestone's website tech support and requested a copy of the MSDS.
