REALLY?
The OP (first post) describes a single wall rim, built wheel with a radial of drop 3mm over the span of 90 degrees (in two places).
Keeping in mind that single wall rims aren't very rigid in the first place, and that this is a comparatively gentle distortion (more ovalized than dented), combined with other clues, I reiterate that seems like much more of a wheel truing issue than a problem rim.
FWIW - It's his dough so I'm not invested in what this OP does. But I want others who might come across this thread to know that this is usually a wheel alignment issue, and not about a problem rim. Were we talking about a 1" deep double wall, semi-aero rim, my answer would be closer to yours.
