No women I`ve even been with has given a crap about her car or what it looks like. When I meet one who does - maybe I`ll marry her.
I did it the other way around, got together with Accumulatorette while her car was, uhm...well, it was leaving rust stains on the driveway and I wouldn`t let it in the garage. Explained the whole thing, starting with "had it been kept clean it wouldn`t have rusted-out like that and you could`ve just kept driving it" and moving on to how "unmarred stuff looks better than scratched-up stuff and it`s all about never touching the paint". It was a classic "lightbulb goes on over her head!" situation and she`s been onboard ever since.
She was unique to my experience in that her car *was* ratty, that was a new one for me as IME most women keep everything they have pretty nice, vehicles included. (Note that in all fairness, its mechanicals were A1 (original clutch/synchros at >150K, overkill OCI, good tires, etc.). She just thought that the Tunnel Wash was OK, didn`t know any better. Bu she did keep the interior very clean.)
Eh, my experiences with the opposite sex always seem, uhm...unusual..in that the gals I know just aren`t the way people seem to think women always are. The whole "women are always [whatever]..." just hasn`t been my experience, but then I`m awfully selective about whom I associate with.
Last person I lent a polisher to was a gal-pal of mine; she did her Lexus with it no-problem and LSPed with M16. Didn`t need any coaching/etc. either, basically thought it was all intuitively obvious. Might not have turned out Autopian, but she was happy and IMO it looked better than when her husband does it.
