Sun film for Maruti Alto K10

I own a 2013 Maruti Alto K10 and want to know how to reduce the glare from oncoming vehicles’ headlamps at night. Is it okay to put a sun film on the windscreen without it affecting night driving? Also, how should I go about removing the dots on my windscreen?

AAA If you are planning to put a sun film on your front windscreen, ensure that it is a 100 percent transparent film, from 3M or a reputed brand, which will not impact visibility. It is quite expensive and will set you back by around Rs 8,000 at the very least. If you go for cheaper alternatives there is a risk that you will reduce night visibility to a great extent and this can be a dangerous proposition. As for the dots, use a professional glass cleaner like 3M Auto Speciality Glass Cleaner, which should do the trick.
