paint protection DOES work. but the only thing is protects the paint from really, is bird sh*t.
everything else gets past it. tree sap. scratches, sun UV rays etc
(as far as i can tell from experience)
just dont park your beloved under a tree and youll be sweet!
the recipe i do, is basically every third time u wash your car (washing average once a week - once every 3 weeks)
do a hand polish, dont use stupid "cut and polish" poo poo.
or that crap the indians sell at petrol stations either lol...
recomend turtle, or Kitten. WAX.
and if u apply the wax by machine the benefits are only better.
