@OP...A Catch-22 (?):
-Many vehicle owners have come to equate water-beads/beading as a "good thing";
when, in fact, after the water beads have dried/evaporated, they leave behind all of their
contaminates---including acids...as unsightly water spots that can stain/etch,
and/or otherwise damage the paint---sometimes permanantly.
Sure, nice photo-op...
But...IMHO...get those water-beads off the vehicle as fast as possible!!
