Just bite the bullet and order the stuff you want online if you can. Motorcycle shops may carry s100 (p21s). BMW on Stevens Creek has some goodies (Klasse, 303). WestMarine has 303 (good price too), 3M polishes and some
Meguiar’s. NAPA auto parts has a decent selection of stuff. Haven’t found any good MF locally. Linens and Things had some but I think they were Nicsand. JTintl, PakShak, YoSteve and Neatitems are all Autopian approved. I’ve looked from the North Bay to the Silicon Valley and only find things here and there.
