Correcting water repellent glass

I have never done any type of glass correction. Nobody has ever asked! I figured I'd give it try on one of my personal vehicles before offering it as a service to anyone else. The problem that I have is my Mercedes has factory water repellent glass on all exterior window surfaces. The only glass surface that needs correction is the windshield. There are random scratches all over it, but not on the other glass surfaces (which is strange).

I don't want to remove the water repellent infusion from the glass no matter what I do. Rain-X only lasts a couple rain storms at most, and this stuff will last a lifetime. It also seems to heavily reject water spotting.

If I go ahead and buff the glass, will it stop repelling water? Will I remove what ever is on or infused into the glass?
 
Hmm, i've noticed on allot of the benzes I do, the glass seams to bead very very well, even though the rest of the car is in very poor shape. Wonder what it is?
 
No one has ever tried working on this glass? Other vehicles have this glass (almost any real luxury car). Some don't last as long as what ever Mercedes is using.

Could be because most of us (assumption) never try to correct glass. Glass is a whole different beast compared to paint and I never attempt to fix scratches or pitting, sans maybe a once over with 151 on a windshield.
 
It sounds like you have given yourself 2 choices:



1. polish your windshield and risk having to apply rain-x from now on



2. don't polish your windshield and find a nice friend to try it out with (maybe offer it up for free as a learning experience?)
