Ah! The sheeting versus beading debate...
Beading simply shows the water adhesion to the paintwork protective coating very low. This used to be the evidence of a good wax coat protecting the paint.
Sheeting would be the opposite to the above and would denote a car that hasn't been 'well looked after'..
Nowadays it's perfectly possible to protect the paint surface but with a film that has very low surface tension, resulting in water/rain sheeting off the paint.
Paintwork thus protected will not suffer from water spots, as there are no beads to dry. shrink and leave a deposit. On the contrary the water will form a film, perhaps just one molecule thick and dry quickly and evenly, leaving an extremely thin even deposit behind. This even coating may appear. to dull the paintwork's shine but is relatively easy to wipe away with a quick detailer spray, leaving a spot free gleaming surface. This is providing the paintwork was properly prepared before the final 'sheeting' coating is applied.
I personally prefer the look of a well waxed car. Mine will still have water/rain beads on it hours after my neighbour's cars are all dry.
