Windshield Repair Forum

Have not got a clue, I have tried to find out in the past but it seems to be a secret. Or is it snake oil I am buying, Most paint shops will use it. Dupont call it 5 drops or something.

I wouldn't waste your valuable resin as a testing product. Rain-X is pretty easy to spot just by testing the slickness of the glass with your finger. You can also spray some glass cleaner on and you will see it bead up and run quickly down the glass.

I also hate rainX because when you try to clean the customers windshield after you complete the repair, you will find that it streaks much more than normal.

Long crack repairs on a RainX contaminated crack are bad news.

OK...all this back and forth...how are you explaining to customers that RainX contaminates...really I was told it etches the glass making it more porous...this made no sense to me given how anything wet beads up on the WS...I've not been able to remove it with acetone I look forward to the duct tape method...is it fair to say that the repair is not compromised strength wise only the cosmetics of it ...I'd really like to get to the bottom of this and appreciate the info...I encounter the stuff more and more each week, its become too available in the car washes...I recently bought a "new" used car treated with it and can't get it off the WS:mad: thanx

Wait a minute...how the heck does duct tape decontaminate the break???

It will not decontaminate the break if has had RainX filtered into the damage by rain, car wash, or washer fluid. If the windshield has been treated with RainX prior to the damage occuring but has been kept dry, the tape will assist in lifting the RainX from the pit and the area surrounding it. The tape may not stick well the first couple of times but it is lifting it away with each strip.

Hey thanx...what you explained makes sense...still back to "IS THERE A WAY TO DECONTAMINATE"...anyone???:eusa_wall

Anyone used that stuff? Wonder how well it works.

Can I recommend a product from Dow products. Its called Betaclean and is available in the US market as GC 800. In the UK market it is Betaclean 3300 and is available from Laddaws glass suppliers. You can see the product on automotive.dow.com. This product is designed to remove chemical contamination from glass and it is the best cleaner I've used. Make sure you follow the manufacturers instructions when using it.

I think I'll have to get some of that GT stuff or maybe the dow stuff if I can find it. As far as the removing rainx from the surface, what I have always done is to use pit polish on a small buffer wheel run at slow speed in a dremel tool. I buff the finished pits this way too, and I know I don't have to use a dedicated tool for this but there is a factor that a friend of mine says is the wow factor. After they've got one fixed by some guy with a Wal-Mart kit, and you bring out all your equipment and finish off with still another tool, they get even more impressed. The buffer wheel does come in handy sometimes for larger pits and for the rainx removal. Just remember to wipe the pit polish out of the pit before filling it or it will be contaminated and ugly looking.
