IMHO, 10 minute drive is too short para masabing hindi effective ang tint whatever the brand is.

Similar sa bahay, in 10 minutes ba malamig na ang room after mo ON ang AC?

Pag bilad sa araw, turn on AC and roll down the windows muna. Nakalagay rin yan sa owner's manual..

Park the vehicle in the shade. Parking in the hot sun will make the vehicle inside extremely hot, and it will require more time to cool the interior. If it is necessary to park in the sun, open the windows for the first few minutes of air conditioning operation to expel the hot air.
