Personally I've gone with 2 products...I use Back2Black first and let it dry overnight or wait until I wash the VX again and then I hit it with Eagle 1 Tire Shine (Silicone of thick viscosity) and let that stand overnight to "soak" into the cladding. I believe that Back2Black kind of dries out the cladding (plus my VX is never garaged and the cladding gets sunbleached!) so I've gotten good results letting the Eagle 1 Tire shine soak into the cladding which seems to give it a pretty long-lasting rich look. If you go over the Eagle 1 T.S. with a towel it won't look too greasy afterwards either so it won't attract dust real bad. Just my .02
