Polish side glass?

I just did it on my convertible back glass.

It does work but does not take out deep scratches by itself. I was able to polish a big scratch to be smooth but it was still there.

I was just using the powder and a small buffing wheel
Well if I can get the side window scratches to look 50-75% better than they look now I'd consider it a success. I plan to buy this kit online ,GP28004 Glass Scratch Removal Kit, glass restoration, glass polish, xNet System.
At 50$ it's better than buying 2 windows.
I'll probably do it right tu after Christmas and I'll post up the before and after so maybe itll help others who have contemplated this route, thanks for the response.
