C & S Shower Door Inc offers two different products that both seal the
surface of the glass, permanently, preventing water damage and
corrosion of your glass during day to day wear.  

ShowerGuard
ShowerGuard is an ion beam process performed by the glass manufacturers
and can be cleaned with nearly any cleaning product.  The Manufacturer guarantees
this product for 10 years.

Tekon
Tekon is a coating, with limited lifetime warranty, that is applied by our own
certified applicator here in our shop.  
Tekon has a 2 layer application that first seals the glass pores and then adds a
hydrophobic layer to repel water and limit the amount of water left on your glass.
This product does require that you use a special cleaner which keeps the seal maintained,
however the cost is about $25 a year needing to only buy twice in that time.
