NO dremel..get ya some polishing/lapping compound around 400 grit or some sand paper in 600 grit and go to it.don't over do it,just a good shine and a slicker than snail snot finish.also polish the under carriage of the carrier,just the center piece where the hammer engages it.
I used a dremmel with a grinding stone to shape my G2 hammer to almost the same profile as the original that came in the kit leaving about .02 more on the g2. Then took the rest down with 400 grit sand paper. I also polished the flat strip on the bottom of the carrier as Dings said.
I consentrated my efforts to just the upper half of the hammer, and while it works great I think after seeing the pics of Ding's I might take it back out and make it all sexy looking too!
