Stealth Limiter...? about technique in use

 So I got this plugin from IK as part of the bogo deal (went with the JimiH. amp pack too)...and have begun trying it out here and there in a song I'm working on.   I am curious if it is standard to use this only at the Master/Final fader....or do you all (as I have done...and seems to give decent results) also place the limiter on individual tracks...ie for each instrument?  I have been reading up what I can find about limiters and get the jist of it...and Im finding interesting /varying results ...especially with the drums (..ie the limiter on the drum track set certain ways ..vs the limiter on the Master).  Then again ...I may be fooling myself that I am really getting a better result vs what I have done ...lol...so bare with me ....I have only just begunnnn .  Thanks for helpful/hurtful/hateful replies ....lol 

i will often use brickwall limiters, 
not as brick wall limiting,
but as color.....
if you set the level just right, 
where the meters hardly even move,
but trust your ears, to hear the change, it will bring the overall level of the track up.......
 
you can set it so it will bring up lower levels, sort of like a compressor,
but it's different with the way it colors and effects the signal.
 
IF your track is clean, with nice headroom, 
the use of a limiter this way will not bring up the noise floor to a degree where it impacts the mix.
 
i have used this technique across sub busses, such as vox, drums, guitars and keys
