I've given up on the latest and greatest whiz-bang waxes that hit the market every few years.
Have used Meguiar's in several flavors including Gold Class and Tech Wax. Turtle Wax Ice etc etc.
I've stuck with NuFinish for the last several years and have been perfectly happy. Easy on. Easy off. Long lasting. In between the yearly wax job, I'll hit it with some Turtle Wax Ice spray detailer to freshen it up a bit which seems to be a winning combination for what I'm looking for.
I'm not concerned about getting an "ultimate" or "deep gloss" or whatever buzzword you want to attach to a wax job. My primary concern is simply protecting the paint. Our alley which our driveway is off of is gravel so its either dust or sandy/muddy splash when it rains that constantly gets on the vehicles.
Also considering I'm not driving any supersexy hey look at me cars (Century, Golf, Taurus wagon) I just don't care. Of course I'm also married, in my 30s, have a child, and have a receeding hairline so its not like I'm going out to cruise for tail like in my younger days.
