I have applied this in the spring. Went thru a brutal PA winter, and asked for more.

I've been happy with Griot's, I go about about 4 months between applications, it'll still be hanging on at 6 months. I've found that when possible using spray detailer instead of glass cleaner will add a lot of life to the coating.

The important thing is to get all the RainX off and out of the system. Cleaning with a rag soaked in vinegar, then Invisible Glass (or isopropyl alcohol), and then Clay bar. Newspaper work well and won't leave lint behind. If you don't pull your wiper reservoir and clean it out you're still going to get RainX haze, learned that one the hard way. Nowadays I put sealant on the glass and keep washer fluid in the reservoir.

I second DBAILEY with PBL Glass. The longest I had it on for was a year, even after a year it was doing ok, but weak. I have put in on a few family/friends cars, never had any negative feedback. I also have Aquapel on my father in laws truck for the past 3-4 months, it also seems to be holding its own. However in my experience with both products Aquapel was a tad more difficult to work with. Can't go wrong with either!

I like to use paint sealants on glass. I find that Chemical Guys Jet Seal or M-Sealer make rain skitter off for a long time.

How do you apply it ? Can you do it by hand ?

yes, just use an applicator or mf towel.

I would have to say Aquapel or Opti-glass. The only problem with Opti-glass is you have to buy so much. Aquapel is very reasonable for the single application.

I coated my wife’s windows with Wolfgang Uber ceramic coating. She loves it so far. I have had more and more clients requesting coating glass as well as paint, so I used hers as a test case. No wipers needed at freeway speed,and glass seems to stay much cleaner now.

I have found that rain slides off with RainX at 50 mph, glass coatings and wax/sealants at 40 mph and a brand new windshield, cleaned, polished and coated with paint sealant will move rain at 35 mph. I just had a new windshield installed recently and was able to really prepare the surface well.

I've used Aquapel as I bought 3 applicators about a couple of years ago, and tried it on my junkmobile Kia Spectra.

I'll advise that it is a testy product to use. It flashes immediately, and the first time I used it, I barely was able to coat the windshield. My advice is when you squeeze the applicator to crack the internal Vial, hold the applicator face up, so that you do not immediately empty the entire Vial's contents into the applicator pad.

Doing such, you then might be able to work with the lightning speed of Data on Star Trek, and be able to possibly coat the windshield, and two front side windows.

One applicator does not go far. I personally would say for the price, it is not such an economic bang for the dollar deal.
