Customer has a car waxed with Meguiar's Nxt/2, and is asking me if I can "Jewel" it. My understanding of jeweling is machine application of a glaze over LSP with a very soft foam pad. LSP is the Last Step Polish of the clearcoat itself, and not a waxed surface. Am I correct, and if so is there anything else I can do to enhance the black cars appearance beyond Nxt/2?
