With summer fast approaching, I was wanting to know what is the best type of Meguiars wax to use on my car during the year's hottest months. Currently for the past few months I've been using Meguiars Gold Class Carnauba Plus Paste wax and I really love the way it brings out the blue color on my Pontiac. But I've read elsewhere on the web that carnauba waxes give up their protection very fast or very easily when the surface of the car gets hot especially during the summer months.
Now I know that It's Meguiars Carnauba PLUS wax, so it's not just pure carnauba wax but it has added polymer protection. But as far as proving the MOST paint protection from the summer sun rays and heat, is it better to switch to a more pure synthetic like NXT 2.0? How does it fair compared to the Gold Class Carnauba plus in terms of heat/sun protection? Also how about the Ultimate liquid/paste wax? How does it stand up?
I may be somewhat ill informed but at first glance I assume that Gold class provides the least heat protection of the three, where as the Ultimate wax would be second and NXT would be first right? This of course, is only comparing the consumer line. I'm sure Meguiars has something maybe even better than all three in the professional line. But anyway, thank you all for your time.
