: I am having the windshield of my E39 528 replaced next week. Well, the glass company asked if I wanted standard or premium glass. Oh, must be premium glass if given a choice. I'm surprised that there was a choice.
: The reason that I'm having the replacement is that I put a zillion cobweb scratches in the glass while aggressively removing Rain X. I've never been satisfied with the cleaning action of the windshield wipers which prompted me to try Rain X. Unfortunately I didn't like the results and had to abrade it off according to the companie's reccomendation. Of course I tried new wiper blades before seeking solutions to the wet vision problem elsewhere. So now I'm going back to square 1 with new glass and hopefully things will improve.
I have been using Rain X with outstanding wet weather visibility enhancement for 10 years.
I clean my windshield with 409, rinse with water and then wipe down with alcohol before I apply an even coat of Rain X. I use a 12x12 inch square of material from a flanel bed sheet as an applicator. If the preparation is done correctly then the Rain X will coat the windshield with a even film that can be hand buffed with no streaks or swirl marks and the wipers are seldom needed. If the Rain X doesn’t go on evenly then you need to clean the windshield again. Holding back on the use of the wipers will prolong the effectiveness if the Rain X. The Rain X will wear off with in a few months. Bon Ami cleanser (made from egg shells) does a excellent job of stripping Rain X and other stubborn film off a windshield without damage. I have also used Bon Ami to clean the windshield before I put on the Rain X, if I couldn’t get a streak free application.
Scotch pads, Comet type cleaners and steel wool are a No! No!
