I've heard of and seen most of them but I follow loads of Instagram pages that are American so that's why. Apart from Megs and Chem Guys obviouslyMost stock chemical guys, turtle wax is here along with meguiars and clean your car holds the 303 range. Others I don't think are held here. But I couldn't see there being a huge difference from them to what is made here. Good few of the smaller brands here use American chemists anyway iirc.
