Just rub a cut potato on the windscreen.

The only concern is that it may disturb your wipers somehow. This stuff is amazing especially on 100km/hr+ speeds, the rain literally just slides upwards and the rainwater are just little drops, so basically you don't even have to use the wiper and you can see the road clearly. The use of wipers actually cause a second or two of unclear sight disturbance as the water is all sweep together.

 

Now the cons, it may affect some wiper blades, not all. The wiper blades require a certain balance sleekness/friction with the glass to maintain a uniform wipe across the windshield without weird skips/judders/jumps/etc. Most formulas contain some form of alcohol, and the chemical reaction with the wiper blades + sunlight = ?

I'm surprised there are still people buying these products for their cars. A complete waste of money.

Modern clear coats on cars have eliminated the need for polishes, waxes etc. The best way to maintain a car's paint coating is to wash with plain water ( NO detergent ) and dry off with a chamois leather. Once a month is enough.

Lighter colours such as silver, white, sand etc. are easiest to maintain. Black and red are bad news to keep clean.

The Vios below is 13 years old, and does not have a speck of rust. BTW, not for sale.

 

 

What a nice car ! It is worth doing such great maintenance !

 

 

Rain-x works, somewhat, but not worth the trouble, overall. Better to have decent wipers. I have used it on exterior mirrors on a big truck, probably the best use.
