Review: Pretty easy to apply just needs another step - This stuff is a very good product. I about a month in and so far it works very well. I have an issue with my new peterbilt 579 where a cyclone develops on the drivers side window when its raining pretty heavy so it makes it hard to see the mirror which in my line of work is super dangerous. So far though it’s working wonders. Is this as easy to put on as RainX….id say it’s about the same. It’s like applying a wax to your windows where as rainX is either a spray or the wipes. I will say the instructions on this though need a bit of work because they say to avoid water for 2 hrs after application but they should add an extra step like RainX does….like applying water to your microfiber cloth then going over the window again AFTER the 2 hours to wipe off the haze left behind. I would say follow the instructions but do this extra step afterwards. I also applied this stuff to my moms Subaru and shes been pretty happy with is especially since rain in the Midwest is pretty much all over the map.
Review: Thank you Project Farm! - Works really, kind of a pain to buff off, but is a solid product

### ⭐⭐⭐⭐ better than the competition, at the cost of more elbow grease
*by A***Z on November 10, 2025*

all the other ones I've tried only start working around 41mph this starts to have the same effect around 32mph so much better HOWEVER it is approximately 300% more work to apply correctly. after application and letting it dry, getting a good buff takes sooooo much more effort and work than all the other ones I've tried. I even busted out my sander and threw on a buffing disk and it still took about 3x as long as with just a microfiber cloth on the other ones. Worth it for me but ymmv
