Re: [ATM] Tell me about scratches

[Ken Hunter <atm_ken_hunter@yahoo.com>]

1. Filter your water supply...

2. Let sleeping dust lie where it is (don't clean
up)...

3. Keep everything covered up when you are not
working...

4. Spritz the air in the polishing area before
uncovering and let the mist settle.

5. No visitors...

This helps a LOT!
