i know some of you are oldschool and don"t like this kind of polishing, but this is not my question. so any advice for hand sanding won't be considerated.

otherwise thanks by adv.

First and Foremost, Please keep in mind that a high RPM machine is best treated with A Lot Of Respect! I've worked around machinery all of my life and I've seen far too many injuries when the Respect of the Machine had been momentarily lost.

As long as you respect the powers of the machine you'll be fine.

If you are going to use a buffer get some 4" spiral sewn cloth wheels. Not only will they get into the contour better, but the surface speed is much less than with larger wheels. Speed ='s Heat and too much Heat ='s loss of temper.

When you are buffing, keep your finger behind the blade as the heat builds your finger will tell you that it's time to pull back and let things cool down.

As far as compounds please remember that the speed of the wheels multiplies the cutting effect so a 80 grit on a wheel can eat through an edge very quickly.

Here's my go to greaseless grits;

80

120

240

400

600

With that said, I like to see what the 600 will do Before I start to a lower grit.

I hope this will be of some help.

OH! I wouldn't be so quick to reject any counsel on hand sanding as there is much that can be done Before and After Buffing to enhance a blade by working by hand.
