DavidB said:The SwirlBuster polish is not meant to be an LSP, even though the durability (I feel) is pretty good. It is designed to be a basecoat product that removes fine swirl marks, fills and seals.
It will work with in conjunction with any wax or sealant that has a low solvent level and no cleaners.

So if I understand correctly, swirlbuster will remain in fine marring as long as it is sealed in. When I say remain in fine marring I don't mean indefinitely, but I would hope it is months and not just a handful of weeks.
