Lapping?

[WeatherGeek]

Hey everyone. I received my Tuniq Tower 120 and the lapping kit of 400-1200 grit paper.

Question: What spray can I use to wet the paper? Do i need to wet the paper?
Thanks
Chris

You can use water or you can do it without a liquid.

Won't water cause corrosion on the copper?

It's fine as long as your cleaning up is good. Someone people also use dishwater soap but I haven't tried that so I cannot personally comment on it.
