I suggest you to contact the glass manufacturer and ask for assistance. But in my opinion it would be easier to simply replace the glass.

Does Regipol 501 really completely remove pyrolitic coating without damaged the glass? Have you try it? Is it difficult to use?

I worked for a glass manufacturer who makes pyrolytic coatings on glass as well as for a glass processor who soft coates the glass.

You cannot remove a pyrolic coating using any means. It is applied to glass when glass is in very hot condition. The coating virtually becomes a part of glass .

By scrubbing you can peel some - but I donot feel you can use that glass in automobiles.

In the QA of coatings on glass (Soft coating as well as pyrolitic) it goes through TABER test - which is forcefully abrading the coating on a glass which rotates at high rpm using sand particles.
Even when after minutes of abrading you can see only 50% increase in light transmittivity .
