Beading is called beading because water forms into a beads. So dapat spherical un.. if it's irregular, that's not beading any more

That's life pare.. if it has wax on it, you'll notice that water comes off quickly (sleeting properties) so what I do is to park the car inside, hose the car with water, and just dry it. If you'll be using the car again, I would recommend you do not wash between.. hassle lang and a waste of time.
Remember, wala tayo magagawa sa Mother Nature.
