A comprehensive session includes pre-wax preparation like de-waxer so to remove the previous wax particles left behind after the detergent wash or road grime and industrial fall outs etc stuck to the paint, make the paint hold the contents of wax firmly and infuse the necessary oils from wax and lastly a ''sealer'' to seal the contents of the new wax on the paint to protect it for another spell of time in which usual shampoo wash could not breakdown it easily.
Well this particular product according to my mere understanding is for temporary use to protect the paint from above said hazards until the proper session,so i am happy with the way it did and is still strong.
