'Crystal Keep' Windshield Treatment

Crystal Fusion is an aftermarket windshield treatment that is suppose to add durabilty and water repelent properties to your windshield. I've never owned a vehicle with this treatment. But it seems to be marketed to behave much like a Rain-X treatment, with longer lasting benefits.

Even though the 2010 Prius V has a water repelent film applied to some of the side windows, on the 2009's I know of no Toyota Factory Crystal Fusion treatment. So this sounds like a dealer added aftermarket addition.

If it's anything like Rain-X, I wouldn't worry about any streaking. It will fade. Just google Crystal Fusion Windshield and you'll get plenty of marketing information about what the whole thing is suppose to be about.

But in general it seems to be a windshield water repelent treatment.

 

If it is anything like Rain-X it has to be wiped with clean rag very hard and the streaks will go away.

 

I've been using Rain-X on both of my cars for YEARS (20+) and never had any problem with streaks. The technique that I have always used is to first wipe it off with a wet paper towel - followed by another (dry) paper towel.

 

Sounds like another expensive dealer add-on that they pay $5 for and charge you $500. I imagine they want you to keep spraying more of this crap on as it is wearing off every time you use the wipers. Glass manufacturers having been working for years for a permanent glass treatment and nothing has worked yet. There are a number of spray on/wipe on glass treatments around, but none are perfect. They all have to be reapplied from time to time, and all have some sort of hazing/streaking problem. I know as I've tried them all.
