Yea, recently met a guy who told me he used the same method and swears by it.

You can buy grits down to 60 or 80 from Gotgrit.com.

Castwell’s sells the glue and grit as well as an “Abrasive Wheel System”, I have often wondered about it, may have to try it.

I use 2 wheels of the same grit so one is drying as the other is in use and try to do all the buffing at one time.

I do keep a 600 grit on another buffer that is great for touch ups and the grit I use most often.
