Scottwax said:I don't get the fascination with topping sealants. Just use what looks best to you. If you have to apply it more often, so be it. Don't make this more complicated than it has to be. Wash, clay, polish, seal.
IMHO the only useful thing to top a sealant with is with a spray wax/QD spray to refresh the gloss/finish after washing. I like Lucas Slick Mist for that.
