Watch a headhunter find his own job - 9 month process
Rain X is pretty awful personally. Too much wiper chatter even with a properly prepped windshield. Aquapel does a pretty good job, is cheap, and lasts a good while, but it's a bit finicky to apply.
Your easy and inexpensive options are to use a spray wax or something after every wash and that honestly works just fine. A lot of times I've used Griots garage glass sealant. The bottle is like 9 bucks and a little goes a long way and it'll give you a good solid 6 months depending on conditions etc.... There's always a glass ceramic coating as well for more durability at a higher price. Lots of options.
Now this was a superior machine. Ten grand worth of gimmicks and high-priced special effects. The rear windows lit up with a touch like frogs in a dynamite pond. The dashboard was full of esoteric lights and dials and meters that I would never understand.
WARNING to Bus guys: Do NOT put it on early Microbus windshields. If the overhead vents are closed the rain goes in little circles right in front of you, but if it's open it goes up... right into the overhead ventilation!

I have found in heavy rain, not using some kind of windshield application is night and day difference for visibility, especially at night.
The problem with using a windshield sealant is it has to be very clean to apply which is difficult in winter, which is why I use rain x wiper fluid at those times.
This was how I determined its effectiveness. Got a brand new car, didn't seal the windshield, winter came. I was on a trip and it was raining/snowing at night and I couldn't see ****. When I got to my destination I picked up some rain-x orange at walmart. Throughout the week I was cleaning the windshield with it and noticed it was beading up. On my way home from the trip it was raining and it was very apparent it was working vs days before.
Ever since I use it in the winter time. I even bought the Rain-x cleaner 2 in 1 spray which I use on cars I borrow from work and even rental cars I take on trips because I think it works so well compared to nothing. It doesn't last long, but typically I only use these cars for days- weeks.
I’m in the camp that these windshield additives never worked for me. What has worked consistently is keeping the glass clean. I clay the windshield a couple times a year. When cleaning the windows, windshield included, 2 cups water, 1/8 cup white vinegar, 1 teaspoon Dawn dish soap and dry with newspaper. The glass is so clean, water will bead and blow off. Blades glide smoothly.
I never really liked Rain-X. Its better than nothing but it doesn't last long and tends to cause wiper chatter as noted. RainX is sort of like putting a dressing on the glass, I believe it is a silicone suspended in a alcohol so it just leaves a layer on the glass when the alcohol evaporates. I'm not a chemist though. That being said if I am going to be driving a rental car and rain is forecasted, I use the Rain-X 2-1 glass cleaner/rain-x because, its better than nothing on the glass and the short duration works for my trip.
For years I have used Aquapel, and I have been very happy with it. One applicator can get me an entire cars glass done if you apply it correctly. I usually apply every 6-9 months. Aquapel actually forms a bond with the glass to fill in the microscopic pores in the glass, This is what Glass coatings/nano/ceramic/quartz/SI02/whatever buzz words are being used do and is why they last longer and perform better.
A few years ago I bought Gtechniq G1 Clear vision smart glass. It's not any harder than aquapel to apply just follow the directions. It lasts much longer and the larger bottles will get you a lot of vehicles done. I believe my bottle is 3 years old and it still works fine. They do offer smaller bottles for one time use. It is my current go to product. I use it on all my cars, my families and my customers.
I have tried Mckees 37 Glass coating and while some people love it, I could never get very good results from it.
IGL Ecocoat Window was another dud.
If your wipers are chattering you have a few options:
Some of the glass coating manufacturers actually say to apply the glass coating to the wiper edge (Geyon for instance) They say this helps with chatter.
That being said I do not get chatter with aquapel or G1 but I also barely use my wipers when at speeds over 35-40mph, as they are not needed. If you apply something to your glass, drive fast, and use the wipers like normal than you probably will get chatter or skipping across the glass.
I do not like using the washer fluid add-ins because the fluid goes everywhere when you spray and if you have headlight washers that use the same reservoir you are just covering your paint with something. It might not last long but it could have adverse effects on different materials.
JEMM Auto Detailing: Cars, Trucks, Motorcycles, Planes, RVs, Bathtubs, if you pay me I will buff it
Washer fluid: I buy whatever stuff is at the gas station and I actively stay away from the rain-x branded or other name brand washer fluids as i find they leave film on the window/a-pillars and other areas not being touched by the wipers.
windshield wax/sealant etc: I swear by Rain-x, I've used it religiously on all my cars since high school and I use my wipers as sparingly as possible. Typically only when stopped at a light because there is no wind to push the water off, and even then I'm manually activating the wiper blades. I'm not OCD by any stretch but I definitely have some odd OCD-like tendencies, wiper blades is one. I cannot stand having them on, in fact seeing other people with them on at ridiculous speeds for the weather at hand bothers me. *shrugs*.
That said, detailers have picked up on this stuff and I no longer apply it myself, I do have a bottle just in case, but whatever the captive detailer guy uses at my office building (comes once a week and circulates between 3-4 buildings downtown) that does my car every other week (hand wash inside/out for $25! or full on detail for $80) works fantastically.
Also, fun fact, use rain-x on your shower doors. Helps keep streaks/water spotting down and makes them much easier to clean. If your wife does the cleaning, its some easy automotive related brownie points. "hey honey, I got this stuff for the car but it'll make your life easier!" You also don't need to do the full on thick application and buff off process since it's not dealing with the elements like our cars do. A light sheen and wipe is usually enough.
Edit to address wiper chatter: I've found that taking a rag/paper towels doused in windex or a light multi-surface cleaner to the blades removes the dirt/grime that builds up on the blades and the chatter stops. I've also noted that because I use my blades so sparingly I replace them at a ridiculously low rate. I think the recommended life span of a wiper blade is like 3-6 months. I think I went 2 years on my last set of bosch icons. So take note of how old the blades are as they may simply need to be replaced.
Speaking of which, the blade itself is super important. more so that it fits/lays correctly on the windshield than the design/brand itself, but I am preferential to Bosch Icons. I even tried other brands of the same design after they started copying the Icon, no where near the same performance. On the other hand, I've had scenarios where the OEM blade really works best.

Instead of using a razor blade, detailers trick is super fine steel wool (home depot, Lowes, etc) with your glass cleaners, then use your cloth/paper towels. Takes all the buggies off pretty well, I use this method on the regular.
I bought a case of the BMW Washer Concentrate and I mix my own with distilled water. I make summer and winter mixes. That isht will clean/melt anything.
Any other fluid will clog the delicate BMW washer motor screen, which sets off an unusually complicated process to find, remove, clean, and replace either the screen and/or the burned out motor. Of f-ing course. Thanks BMW.
