Ya got an angle grinder, good respirator, and a big fan? Go to Lowe's and get you a DeWalt diamond cup grinder...about 50 bucks IIRC. Grind your high spot down. Probably won't take you 30 to 45 minutes. I surface ground the floor in the Pink Room in about 2 hours. Actual grinding time was about 40 minutes, but I had one window to exhaust the dust from. I could grind a cloud to the point I couldn't see the floor 2' away from me in about 5 minutes.
If the original patch is holding, why try to take it back out? Jim.
edit: Be sure to get the double row cup instead of the single row. Easier to keep from digging into the surface creating grooves.

At a minimum, I'm Pentatoxic...but most likely, I'm a Pentaholic. There seems to be no known cure. Pentatonix, winners of The Sing Off, season 3
