I understand that but the amount of wax that's left in a chip if you wipe it off is inconsequential volume wise. I've done touch ups both ways, solvent prepping and not and there's no difference that matters. No difference I can detect even after years - I test on my own cars.
On the other hand, I'd never paint over a whole panel without prepping it first because that's a different situation. The wax will bead up and fish eye paint like crazy, but over the small distance of a chip, there's no effect. Of course, you're technically correct, but balance that against having the whole panel without wax or trying to clean the wax out of just the chips and the advantage is less than the disadvantage. Like I said, the solvent in touch up paint eats through wax and doesn't interfere with adhesion so I don't bother.
