| lol not quite done yet ..but ok!lol
while your sanding, the paper will take on a dark copper color...and that's ok.. but once you start to see shiny patches, take cloth and wipe the paper down. you should remove all of the excess copper and continue...don't forget to re-lubricate your paper!
sone people like to use dishsoap for extra "slide"..this is detrimental to lapping, as the soap will coat the surface of the paper and the 'sink, causing u to be sanding more soap than 'sink.
