Step 3. with a hand pad I continued sanding away 80, 120, 240 320, 400, 600, 800 and even 1000, although I don't think the 1000g did much but choke the pad. 

I know I might have been the one to inform you about Abranet, however, isn't this taking it a tad too far... or am I missing something more than a fair distribution of brain cells?

I usually sand to 240, and perhaps 320 (if I lose count), but after that it's over to the buffer (if I'm buffing)... I've found that the Tripoly, White Diamond, and either U-Beaut polishes or Minway (for acrylics)removes the 320+ need. 

If your first cut is too short... Take the second cut from the longer end... LBD
