I know this is going to sound a lot like my position on observing towing capacities, but the ZEP product label clearly states that it's not for use on "Painted Concrete". For that reason I would be very careful about using it on cured (meaning at least 6 months old) paint
and would hold off all together on using it on fresh paint
You might want contact the mfg about using it on painted surfaces of any kind before you trust your new paint
job to it.
