Few Question About Glass Waterspot Removal..

[Stevenzee]

Hi AutoGeekers.. I'm newbie here and i'm Indonesian.. So, sorry if my english is bad..
I want to share my work today and there are few question i wanna ask..

I'm frustated about waterspot at my car glass..
Few days ago i tried Glass Science Glass Scrub + MF Hand Applicator Pad to remove waterspot. And no effect at all..
Then I'm using full power elbow grease tryin' to remove that thing.. And still no effect.. :doh:

And todayy.... I encourage myself to polish my glass with DA + MF Polishing Pad + Glass Scrub.. The result was good..

But, i have some question about my work..
1. Is that safe to polish glass with MF pad + DA? I'm use 5-6 speed..
2. I'm afraid, i can break the glass because the pressure and the heat generated by machine.. Can the glass gettin' thinner and suddenly break?

Here's my tools

Sorry to thread jack but has anyone used chemical guys water spot removed for glass? I briefly tested it and it worked but didn't give me 100% results. Seemed like I need to serious elbow grease to get it all out

I think you should use more aggresive pad. Because, yesterday when i tried to remove waterspot, first i use foam pad and it didn't removed 100%..
Then, i switch to mf polish pad and it's completely removed..

or maybe you should try with carpro rayon disc as mentioned above..

Good job removing waterspot on glass!

I always use rotary and foam cutting pad. Working with DA takes too much time and energy. You can use glass scrub or even cutting polish.

Glass is much much harder than a car's paint, so you will do less harm to it, but you still have to be careful though.

The reason i use rotary is because i dont have to put pressure. But i am glad DA is working for you.

Thanks, ko.. Haha.. Seems like i hv to add rotary in my detailing arsenal..
Yap it's work by DA.. But, i hv to use heavy pressure to remove that waterspot. I'm afraid that i push too hard then i'll break the glass..

And after you said that glass is much harder, i can be relax when i polish the glass..
Thanks a lot, ko.. :D

Do you use heavy pressure with that combination?
Or just light pressure?

unfortunately i can only do this by hand :/ the results weren't horrible, but the water spots weren't 100% gone either

The heat is the main concern when polishing glass... if you notice excessive temperatures, DO NOT then spray it with a cool water. Drastic, rapid temperature changes can cause the glass to crack/shatter.

Keep the surface of the glass wet during polishing - the water on the surface will work as a "heat sink" and will help to keep the glass cooler.

Can you tell me the best method to keep the glass wet?
Left hand spray with water while right hand polish the glass? Or just focus to polish first, then stop few times to spray the water and continue to polish?
