[updated]: Art Of Gloss Nonna

: You cannot hide flaws under gloss; the finish only amplifies what is beneath.

Month 1-3: Explosive water beading (tight, tall beads that roll off at 30 mph).
Month 4-6: Beading diminishes to sheeting, but chemical protection (bird droppings, sap) remains effective.
Month 7+: Acts more like a quality sealant. For a spray product, this is above average, but don’t expect the full 12 months if the car is not garage-kept.
