Scratch removal from BMW glass

Hi friends

We are dealing with a case where water spots removal from automotive glass using the wrong products (acid based solution and inappropriate pads) has simply made the glass worse, creating marring from the use of aggressive acidic solution along with loads of scratches.

While there are glass restoration kits available online, in most cases it is not possible to remove a scratch on a DIY basis unless you know what you are doing. Else you will put further micro scratches which will make things even worse. You will also have to cope with the heat generated by the process which can crack the glass as well and the greater the chances of lensing in case of uneven material removal.

Automotive glass needs 100% clarity and vision has to be perfect. Period!

Tools and products used:
- Makita rotary with small festool BP, felt pad
- Cerium oxide powder mixed with water to have a paste



Correction underway

After a few hits, the LED lenser being very useful.

Deeper RIDS can be seen now and need a few more passes

OMG!

looking closely you could see the lensing effect. same object appearing at different distance, with different levels of clarity from different spots of the same glass, and this is unacceptable for automotive glass and very very risky for drivers as well as pedestrians
