It will depend on the polish, pad, tool, and person using them, but in my experience a light to moderate polish will remove it on the DA with a polishing pad in 1-2 polishing cycles.
For testing purposes I was able to rub through with Opt Compound II by hand in a small section. It's not really visible when you rub through, but the beading characteristics will be gone after an IPA wipe-down and frost or morning dew will look different around the areas that have no coating...dust/dirt even attracts differently.
