Welcome to the forum! I'm an "older" guy too (75), and just spent the day detailing my Equinox (black) before winter starts. I get real good results with the Spray Graphene Coating, but I also take the time to follow all the steps and do it right (wash, clay, polish, prep, coat). I'll have to get some pics tomorrow. Looks pretty darn good. But the spray coating is a lot more forgiving and easier to apply than the regular graphene products. Lasts about a year with proper maintenance.
Nice looking truck youngster!!
