For me its got to be:
Wash: P21S
Sealant/Polish (Chemical): CarLack68 /
Klasse AIO (same thing)
Polish (Abrasive): GEPC (though normally drop in favour of CarLack as I dont need an abrasive polisher)
Wax: P21S Wax Paste is still king but Natty's is growing on me.
QD: FK1 425
Pads:
Menzerna Germany
RO: PC7424 of course
