I use an old arm, cover shaft in toothpaste and add more as needed. Stick the arm in a dremel or drill, slide the bushing into the arm and let it rip. Hot water takes all the toothpaste off.

it makes no difference, ive done it, it makes the bearings spin freely like bearings but you wont notice anything.

You'll feel a bigger increase in power as your cut the comm down, but I like to think prepping the bushings does something. So no, the change isn't dramatic but I think it would show on a dyno.

you will get more power out of motor (all brushed motors for that fact) if you true the comm right down, whether or not you polish the bushings.

If you want to make a motor go fast at the exspence of armatures, true the comm down untill there is nearly nothing it will make it really fast.

Yes my responce was very cloudy. I just woke up.

What I ment was that if you put in prep'd bushings you will feel less of an increase in power then if you cutt the comm. imo.

dontfeelcold - I have an mvp with an arm that's amost dead, it is the fastest it's ever been.
