Dear Knucklehead,
I own a 2017 Palazzo, which is painted and have just used F11 Top Coat which is a silica dioxide polish. It is so easy to use it should be illegal. It is more expensive than auto polish but the ease of application pays for the additional cost. Less time up a ladder and much less buffing, just two microfiber cloths which you can buy with the polish ( on line only ).
I have used it on my Equinox towed which now shine like the sun as does the Palazzo.
I wanted something very hardy living as I do in Buffalo NY and have to deal with Sun, Snow and particularly road salt.
There are many other Silica Dioxide polishes available, check on line and take a chance, I think you will not be disappointed. One caveat, it needs to be not too hot when applying and must have a couple of days without rain to allow it to fully bond.
Good Luck.
