I have used Chemical Guys Citrus Wash as a stripping awash prior to clay. Afterward I washed with it again. I have a 2010 Ford truck and the paint is in excellent shape and after this process I am amazed at the finish left behind, so much so that I got to thinking....What am I gaining by additional polishing and sealer rather than simply applying a coat of Optimum spray wax (which has sealer) and maybe followed with BF spray sealant? I suppose the durability won't be the same but after each wash I usually wipe the truck down with Optimum spray wax or BF spray sealer anyway.
