Hello gents,

I purchased a nice DMT D6E, but I haven't used it yet. I think it would be wise for me to ask you if there's anything I should know/do before using it.
Should I lap the DMT? If so, should a 360 grit sandpaper do the trick?
The DMT is one-sided only? The side that does the work is the one that is the topmost face when laying the DMT and the label on the side is not upside down, right?

Thanks!
