Bro, this sounds weird, but can I use it for bathroom glass? I am really sick of my bathroom glass having water mark and impossible to get the hotel type clarity.

If can, PM me for both water mark cleaner and subsequently the nano protector coating thing. Include shipping to Seri Kembangan.

Similar to the nano liquid coating, I bought this some time back from ra2boy to try out on my shower stall which is made of glass. You can read my review of the liquid in another thread (it's good!) and similarly, just disclaimer first that ra2boy didn't pay me or something to write this.

This watermark cleaner works rather well as you can see the difference even as you are applying. The glass will become smoother with less marks (I saw less cos my shower stall is not like car windscreen lah, always splash with water few times a day, so the watermark and soap scum is quite bad despite weekly cleaning).

The only thing with the powder is that you really need to have plenty of patience to slowly rub away the watermark. Actually, for those who complained of tired arms, I find that it helps to not use brute strength too much, but slowly "massage" the glass area until clean. I also find that you tend to need quite a lot of powder since the powder will be less effective as you scrub, so need to top up from time to time.

But in summary, this is still a great product. Be prepared to spend some time and energy to do it and you will feel satisfied with the result. Price reasonable especially seeing that glass treatment for cars are pretty expensive at detailing centres. After doing this, I strongly recommend the liquid coating (can't say enough good things about this one).
