PinkAway, when applied during warm or hot sunny days and with the treated areas directly exposed to sunlight, pinking can be fully eliminated after 5 coats are applied over a 2-3 day period.  In fact, under these conditions the pink stains will appear to be fully eliminated by the second day.  However, looks are deceiving.  Any stain not fully treated with all five coats, as per instructed, has a very high chance of reemerging .
