I'm getting ready to start detailing my vehicles and want to get an idea if these polishes and sealents will be good and also which wax i should use. The cars I have are a 2006 hyundai sonata (silver) and a 2007 Hummer H3 (white). On the sonata I'm going to use the Menzerna instensive polish, final polish, and wolfgang sealent. On the Hummer is the final polish, and wolfgang sealent. What would be a good wax to top this off with? I live in Houston where it's hot and humid and I only want to have to detail the cars like this every 3 or 4 months. Is the Wolfgang a good enough polish or should I look at something more durable. Also would the sealent additive help? Any help would be appreciated.
