if you can feel them with a fingernail, they can't be gotten out without some distortion. for a front door glass, that may be acceptable. for a windshield, it's not.
you can polish glass with very fine abrasives and water, lots of water. if you do this without enough coolant, the glass cracks. it also takes a long time.
you can get a pretty good polish with cerium on a felt pad.

How difficult is it ? got a few scratches on the front door glass and a few on the windshield.
Thanks
Last year I bought this kit from J.C. Whitney and clened some scratches off the windshield of son's new to him car. Looked like a wiper blade failed or fell off as there were several arc shaped scratches in the glass.
Took me about an hour of work with the buff chucked in a variable speed drill, but all the scratches polished away fine.
You look *through* a windshield, not *at* it, so a tiny bit of distortion caused by a little extra curvature here and there on the glass surface gets lost in the noise caused by the movement taking place when driving.
HTH,

You can buy a smaller kit for half that price on eBay. If you don't have to do 25 windshields...

Check your auto insurance. It may cover the windshield (not likely the side glass).
