Here it is:
Here are some pictures of the valve job on a G7 done with a Dremel Tool and the polishing kit
Please note that the abrasive used is the one that Dremel sells, anything like braso or such will burn at such high speeds causing a reverse effect. Use and abrasive specified for high speeds or the one supplied by Dremel.
When you take the stem out, it feels a bit rough.... after the polishing is done, one should not feel any roughness with your fingernail, it should feel like it is glass.

Prepare the dremel bit by ataching a felt wheel, the abbrasive is kindda dry, but with the dremel in motion you can scrub the felt in the abbrasive and it smears on the felt. Do this as well with the Qtip procedure ahead
Polish only in the direction of the travel, meaning at up an down the stem, not around.

BE EXTRA CAREFULL NOT TO WEAR OR POLISH THE PLASTIC SEAL!!!!! The only part of the stem that really needs polishing is about the first centimeter of the stem (starting from the top, being the top the stainles steel guide). This is the only part that has friction. Above that is just for the bling factor.

It takes a while using only the felts and abrasive... if you start with stell wool (wich is more coarse) it could take shorter time.
I adapted a plastic Q-tip® cut in half to the dremel mandril and it fits perfectly... this is to polish the small hole in the valve (the guide) so the friction is even less... Don't let the valve get too hot and remove the orings first so they don't suffer from heat expantion. Do baby steps... little by little.... let it cool down and resume.... USE COMMON SENSE (by far the least common of senses) DONT OVER DO IT!!!

Clean all surfaces with a household solvent... NOT THINER.... clean only the part of the stem you polished. The valve can be submerged in solvent without the orings (the solvent may disolve or wear the orings)
Then its regular detergent and water..... Clean the valve with more Qtips
I polished the whole valve (the outside and the accsesible parts where air flows).... I had the time and the tools... just for bit more bling points. This is not necesary... although, like in cars... polishing all ports help.... its a very small difference....
Let the pieces dry, Regrease, reoil, reasemble (don't forgget the orings) and gas your gun up.
It might leak a bit at first, then the valve, seal and stem settle again....
enjoy
