Tell me more about rainx. Sound interesting.
I haven't had any negative issues with it, but sometimes the bugs can be difficult to remove.
Once, it was recommended for plastics. I used it on tail lights etc with good success, but I see now on the directions, it's not recommended.

RainX is great when freshly applied, but it wears off quite quickly, then it starts to go slimey and smear (especially in cold, damp weather with a cold windscreen). I found I was re-applying it every 4-6 weeks unless it rained a lot, when it needed re-doing even more frequently.
These days I use Aquapel, which is not quite as good as fresh RainX for water beading, but Aquapel lasts for 40+ weeks, which is much better (but of course it costs a lot more than RainX). NB I have no connection with Aquapel, I'm just a satisfied customer.
If you decide to remove RainX from glass, I've had good results using Amway metal polish (but wet your window first, apply the polish to a wet rag and rinse very thoroughly when you've finished).

If you keep your windscreen clean then I have found no advantage to the Rain X type products. I regularly clean mine with Nxt Glass Cleaner - which is tint safe for inside as well, and periodically polish the windscreen with Autoglym Glass Polish.
