My brother-in-law purschased a 2013 Black GMC Sierra 2 months ago and put a coat of wax on it just 3 weeks ago, I told him he should have put a sealant on first and then a coat of wax. What do we have to do now to put a sealant on, wash the truck with Dawn detergent to get the wax off and then clay before putting on sealant, followed by a coat of wax? Any advice will be most appreciated, thank you in advance.
