on average, with my car (I park indoors 9hrs a day 5 days a week), 15km daily trip or so... with the usual rain, sun, dust, 3x a week wash... a layer of wax lasts no longer than 1.5weeks or 9-11 days... after that, wala na... kung sealant, mga 3 weeks...

Does the "3 weeks" also apply for "Klasse Twins" that I reinforce with Mothers FX?
