Fogging ng rear windshield from the outside

[torbiks]

Malakas a/c fan and thermostat mo kaya abot sa likod kaya nag moist sa labas. Pag sa loob ang moist, init yun against colder outside temp.

naka-lowest na yung fan ko, sir...pero subukan kong ilagay sa gitna yung thermostat ko the next time it rains..

thanks sa lahat ng sumagot

Why not try Rain-X products? Or even Rain Away (by Turtle Wax).

Yung Rain Away, dual purpose. Meron anti-fogging and helps water bead away easily. Less than P150 lang sa Ace Hardware. Although based on my experience, pahid ka ulit after a week.

does those actually work? never tried one. waste of money if equipped with rear window defoggers.

Yes they do work but you have to re-apply about once a week for best effect.

To conserve on the product, just use it on the windows you need like rear window and the front side windows only.
