Beads of Water on Side Windows Hamper Visibility

Rain-X or if you want something that lasts a bit longer (on the windshield - On side windows Rain-x is fine, it'll go a LONG time) go with Aquapel: single Aquapel Glass Treatment, Rain Repellent, glass sealant, windshield protectant, Aqua-pel glass wipe case Aquapel Glass Treatment - Case of 6

 

Just asking, but what made you want to apply it on the inside?

 

You probably know this but rain-x makes a product for that, rain-x anti-fog, but it certainly isn't the water beading regular version of rain-x.

I just just wondering their reasoning for applying it on the inside.

 

Ahh, ok, I thought maybe you read somewhere it has some type of positive 'effect' if applied on the inside and was wondering what it may have been.

 

Rain x beads are tighter beads and roll/fly off considerably easier than on glass without rain-x. It's relatively cheap for a bottle at say Walmart, maybe $5. Can't hurt to try it. And even if it doesn't help with your situation it honestly makes a considerable difference with windshield visibility.

 

Rain-X makes it easier for water to bead (rather than adhere to the window) and hopefully run down because it forms bigger droplets that overcome the friction coefficient of the window glass.

Toyota briefly offered water-repellent front door glass on the 2010-2011 Prius (mine has it). It works not too bad. You do have to keep it clean so that the water repellent properties work. (If the window has a layer of dirt or grime, then obviously it won't work) and water streams off nicely at suburban speeds (roughly over 30km/h) in light rain. Moderate rain will definitely keep it clear as the amount of water on the side window is enough that the droplets will coalesce and slide down on their own.

 

Maybe polish your glass with glass polish, I've got no idea beyond that for what you are experiencing and how it's affecting you.
