Yeah like sandpaper right? Different grades etc
Forgive my ignorance, do you mean sort of like a sponge for foam?
Yeah kind of like the sandpaper. You get ur general purpose ones then plusher ones for removing waxes and polishes then an even plusher one for drying. Microfibres with silk edges and one with no edges.
The list seriously goes on.
This is the foam applicators I'm talking about. You get better ones that are three layered that give you even pressure when applying but these work just as well.
