Protecting and "Rain-Xing" a BMW windshield

[r12r-don]

Just got off the phone with Rain-X. They say don't use their product on plastic. HOWEVER, they did recommend Aeroshell.com - under flight jackets is the following:

AeroShell Flight Jacket Plexicoat

Extends the life of your windows and increases visibility. Protects from harmful UV yellowing and cleans away dirt, oil, and bug stains.

Prevents windshield from yellowing and clouding
Removes bug and oil stains
Eliminates light surface scratches

However, it doesn't say anything about smoothing out the rain droplets. Anyone try this or have any other rain-x type options they have been using? Am most interested if you've been using it a while and can attest to how it works over time.

Thanks for any input.

OK - the answer to your question. Rejex. It's a polish originally made for aircraft use - on their windshields. It works great on bike shields, face-shields, headlights and even your bikes paint.

Tricks to using it..

- Multiple coats are a good thing - it builds up on the surface in layers
- Space your multiple coats out by 24 hours or so - if you don't the new stuff will tend to dissolve the originally hardened layers and you get no gain in protection
- It does leave the windshield VERY slick - which means the raindrops just sort of flow up the shield pushed by the air. There is no "sheeting" action
- Don't worry about getting it on black plastic bits - it doesn't leave white stains behind. I actually use it on my side-cases quite regularly - to help remove the heel marks I get on the right side one.

Interestingly enough - when I bought the Cee-Bailey screen for the Roadster, it came with a small bottle of cleaner/polish for the screen - with Cee-Bailey's name on it. It smells and seems to work exactly like Rejex - If I had to guess - it's re-labeled Rejex.

Good stuff..
Bugs will come off lots easier, as will bird poop. I've been using it for about 5 years now - and one bottle of it still has about 1/2 left, I've used it on several cars, and extensively on my bike.

I've used Rain-X on Shoei face shields for over 5 years with excellent results. I did this on Shoei's advice, not Rain-X's.

I suppose Rain-X is in CYA mode when they say not to use it on plastics. There are lots of plastics out there and they don't want to take the chance of damaging something.

I'd bet BMW knows the answer. Anyone ask them?

I use Rain-X on my CeeBailey screen without problem, and also on my Shoei face shields.

Somebody needs to tell the helicopter companies in south Louisiana too... they use it by the gallon on the high-dollar screens on their birds.
