that rubbing compound looks great.....I'm wondering if it would take a few of the scratches out of my 55 gal too. I'll have to pick some up since short of pulling out the HCl in my test kit, I don't think that all of the haze will come off.
not using CLR....I've read enough of gunner's posts to just follow his advice at this point. The rubbing compound is working great, although I've discovered that at some point the previous owner did use something a little more abrasive and I've found a few scratches on the inside of the glass.
