congrats, that's one of the best car care products i've ever used. it's pretty much used like a polish - it's job is to replenish the oils in the paint and restore deep shine...it can also take out light scratches if you buff it on there.
you apply it before a wax, it lightly covers up swirls and stuff... it doesn't really replenish anything since paint itself is non-porous, but it coats a layer of film on top of your paint to make it look really wet...
Please follow the instructions sa bottle, otherwise mahihirapan ka magtanggal.
