I plan on applying 22ple VX Pro2 to my black Lexus IS250. How does the 22ple VS1 Final Coat compare to something like Meguiar’s Synthetic X-Press Spray Wax D156? Should the D156 be used instead of or on top of VS1 Final Coat? Or, is there no need for D156 if I’ve used VS1 after the VX Pro2 coating has a been applied?
