Aquaglide applied on Starphire glass by hand?
We are doing Starphire glass on some of our shower doors. The shower door company owner says the only protectant that can be apied on Starphire glass is Aquaglide, which they will apply by hand. "By hand" screams inconsistency of finish to me. Is this commonly applied this way? Is it worry it if you have softened well water? Thanks!
