Hello,
The suggestion has been posted here a couple times to use RainX to seal glass shower enclosures, to improve water shedding and help prevent hard water deposits. The bottle of RainX I bought recently says it is for use on "exterior glass". Is there a different product for interior glass? Or can I use this product without gassing myself? BTW, how long does an application usually last (2 showers/day)?
Cheers, Wayne
