For the longest time I used RainX windshield cleaner but it never satisfied me. Always left my windows with a streaky smudgy finish.
I recently bought Invisible Glass with rain repellent and a can for window tint(foam). Over the past few days I drove from SC and been all over FL. (now heading back to TX). As I was filling up this morning I decided to clean my windows, try this new stuff. Let me tell you that stuff works! It got my bug infested windows cleaner than a Sunday school teacher and didn't even attempt to streak.
For using it in 35 degree weather with no issue, its now the window product I back up... only wish I found it sooner! I highly recommend it!

 

Invisable Glass is all I have used for years, though, I have not tried the one with rain repellent.

 

If I hit rain I'll let you know how it repels. I now joined the elite class with you my friend haha!

 

Never tried it with the rain repellent. I been using the reg Invisible glass for years and love it, then usually top with Rain-X.

I'll have to try it once I run out of reg IG.

Edit: Safe for tinted windows too, the main reason I originally picked it up.

Prima Clarity is awesome or Stoners Invisible Glass if you want something that you can get locally.

 

The regular Invisible glass works well, that's what I use. Anyone know if it works well on the inside, like the windshield?

 

Invisa Glass was all I used for years...until I had a free sample of Mother's glass cleaner. All I'll say is I never looked back. Invisable glass in the aerosol can is good stuff though.

 

I've switched to Stoner's Invisible Glass as well and it works well and the only time it's ever streaked on me is when it was used on extremely hot windows.

 

Another fan of the I.G, years with great results, better when I discovered microfiber cloths. The other I'd suggest for exterior only unless you have no tint is Volvo glass cleaner, used in trucks, and AC Delco glass cleaner. My company use to stock the trucks with these and when I was bored I'd clean the windows. Those foams worked very well like the I.G does, more foamy though.

 

I have been using the Zep glass cleaner from HD. Use it with the bug cleaning MF cloths from PB World, and it will get a nasty windshield clean in no time flat, no streaks.

 

Stoners is very good as is sprayway, but a 50/50 mix of denatured alcohol/distilled water is the best, cheapest!
