^Also availed of their glass-polishing service a few months ago. I noticed I have some tough watermarks again. Not so sure if BB were not able to get it off or those were newly developed ones. Nevertheless, those are some tough marks to remove.

Yung malabo, I noticed this on my side windows. Its like the water is not beading as usual but instead, it was flowing down (leaving behind trails) which reduced visibility. Again, I dont know if its the result of the glass-polishing.

Also you mentioned yung malabo ay nasa windshield mo during wiper operation, perhaps the wiper blades need to be replaced?
