is this for electric motors?
if so they probably are comm drops. Personally the only comm drop I will use is the tribo stuff. it works and is some of the best stuff I have used. I wouldn't use any other stuff.
If you are set on using these drops, basically you put 1 drop on the comm or a tiny drop on each brush ( comm seems to work better at least for tribo ) and they are susposed to give you more power, etc. Thing is they can gum a motor up ( tribo doesn't do this ) especially in offroad.
Tribo works so well that I even use it on some of my bearings as they seem to last longer than before.
I love tribo !
