Meguiar's vs. Zaino

[C230K]

Check out this long article I found about a test between Meguiar's and Zaino.

In step 10 of the test, the owner removes the tape that separates the two polished areas and then shows the area that wasn't polished--the swirl marks are almost the same in the Meguiar's, Zaino, and unpolished areas. Interesting. What do you all think?
I use Meguiar's with good results and it's easy to run down to the store a get vs. Zanio mail order only. Both great products.

I wasn't aware that Meguiar's made a polymer sealant. Polymer sealants are certainly superior in both shine and especially longevity to conventional waxes. I really like Zaino, but it sounds like the Meguiar's polymer sealant is good also.
