Experimenting with chain lube application

Its a very beaten down subject similar to engine oil.
Lets have a holistic approach to this subject.

O/X ring chains are sealed with grease. So, it is ur job to keep the o-rings supple and the exposed metals from corrosion.
Yes, solvents should be avoided as they might affect the life of the O-rings. But sometimes, its a choice between the "might" and the grinding paste.

An ideal chain lubricant should have these properties
  1. Tackiness (adhesive/cohesive properties) – excellent adhesion to the gears or drive train to be resistant to fling off
  2. Resistance to water washout and spray-off
  3. Load-carrying capability to protect against friction and wear
  4. Protection of the gears against wear and corrosion
  5. Cushioning ability (vibration reduction)
  6. Sprayability and/or ease of dispensability
  7. Alleviation of housekeeping and maintenance problems eg buildup in the roots of the gear teeth
         WD-40 or similar products does a superior job in many aspects except point 1,3 and 5.

         Therefore the other product you use have to be great in the lacking aspects. Also, these  
          aspects is needed only in the rollers, bushings an sideplates meeting the O-ring. In short,           the middle of the chain and not the sideplates.

Its a dirty time consuming back wrenching job.

First step is preparation.
Plain ahead and prepare items.
After coming home from a ride,

1. Soak the chain in a WD-40 or a similar product.
2. Let it sit for a minute or two.
3. Use a rag to detail the chain and gears. Allow solvent to dissipate. 
4. Use a small paint brush with the bristles cut to a length of about an inch. This is to stiffen it up and aiding in precision application.
5. Depending on your conditions, choose a chain lubricant to suit your riding conditions. My favourite is the 80-90w gear oil. Spray that lubricant or gear oil into a small cup. Dip your brush in the solution. Apply a very thin coat onto the rollers and o-rings. A rule of a thumb is to only have to re-dip the brush once and apply only a single coat. 

You are done. If possible, let it sit overnight.

UPDATE(It rusted within a day on the top links. Probably becaused I wiped off the wd40.
ARGH!)
