Recommendations on a wax, please.

willz370

I hand wash with rain x wash and wax dry a with shammie polish a couple of times per year with Black Magic Wet Shine Liquid Wax. Buy it at your local Wal-Mart its inespensive and works great my 370 is Black. Prior to that one I had a Black 350Z leased for 5 years, it looked as good as day one upon return. I keep it outside covered with a Nissan Z cover the finish its so slick after the rain the other night it had no rain drops showing after driving it to work. My only issue, it hard to get the cover on, it just slides off the side that is irritating.
