what wax?
water spots is minerals that form with water droplets and dried on the surface
waxing does not really cover these imperfection spots
so the water still attracted to these area
to remove, simply get meta clean is enuff
and some major elbow grease
considered more "easier" gyeon water spot remover
does able to remove to a certain extent, but seems to need to use quite a lot if the spots are severe
also water spot remover is not that compatible with glass, though usable, they dont recommend it, as glass is still made of silica minerals
i use mothers carnauba cleaner wax.
actually the panel is initially clean, no waterspot. then i wax it. then next day i try spray water, the day after there are water spots.
