Many people think that if polishing can “bring glass back to life,” then coating no longer has any real purpose.
“If polishing can restore a glass full of stains back to normal, why should I bother applying a coating now? I’ll deal with it only when the problem appears.”
This way of thinking is completely normal. But I want to tell you — polishing is not the perfect solution.
First, your glass will never return to 100% like-new condition. How much it recovers depends entirely on how deep the stains have penetrated into the glass.
Don’t underestimate these water stains —once your glass isn’t protected, they seep into the microscopic surface layer. That’s why ordinary cleaning doesn’t work.
Polishing only works because it uses very strong acids combined with a polishing machine to grind away the top layer of the glass.
In other words, the “permanent stains” are removed by shaving off part of the glass surface, which means your glass becomes thinner.
And then all your effort goes to waste. When the stains come back, polishing again may no longer be an option —because if the glass becomes too thin, there’s a real risk of spontaneous breakage.
And then all your effort goes to waste. When the stains come back, polishing again may no longer be an option —because if the glass becomes too thin, there’s a real risk of spontaneous breakage.
That’s why, eventually, you will still rely on a protective coating to stop stains and etching from attacking the glass again.
So for every customer who requires a polishing service, we always recommend applying the coating immediately after polishing.
But many people find it expensive —because it means paying for polishing and coating.
Which is exactly why, while your shower glass is still new, you should apply a protective layer now. Do it early — and avoid these problems altogether.
