u might want to try using 3m imperial hand glaze.this is body shop safe meaning it contains no waxes or silicones.technically a qd does not provide any protection at all.the glaze will give u a wet look but will last a few days only without wax. ur right that u cant wax for at least 30 days or more pa nga.also take note some qds have carnauba content in them.
