What am I doing?

sounds to me like your maybe trying to clear up some foggy headlights? but why the putty knife?

you are correct. and holy cow i googled this method and its working like a charm after my GM dealership f'ed up myone headlight last week. the putty knife is meant to scrape off grime and some of the "film" without making scratches on the lense. what worked better was degreaser. tomorrow i'm moving onto step 4, but goo gone, degreaser and putty knife have already almost 100% corrected my lenses. i have no doubt that after the alcohol and just a tiny bit of sandpapering i'll have headlights looking brand new......and mine were AWFUL!
