Re: ATM Polishing and still have pits

[Peter <kitgears@kitgear.com>]

Hi Mark,

I had the same problem until I polished with the tool on top. Works
about 10X faster for the edges. Just be very careful that dirt sunk into
the channels of your lap do not scratch the mirror. I wash my tool with
a tooth brush every time I use tool on top.


Cheers,


Peter
