Answer:
Answer 1)
It is almost impossible to allow it to stay on the waterline as your tears naturally have enzymes that breaks thigns down. From what you said, I presume you have slightly watery eyes as well...
The only way is to carry ya kohl and touch it up when it fades off.

Putting an eyeshadow after the eyeliner is place on the WATERLINE will NEVER help as the waterline will feel too dry and your eyes will tear even more.

Some will suggest mixing with glyercin (which is a foolish idea!!) but because it is the waterline, your own eye balls might feel irritated from the glycerin present.

The only way is to use waterproof pencil liners, which will fade off but resists the tears longer than normal kohl pencils.

Answer 2)
For someone with a watery eyes. You will find that most eye lining product even MAC's PowerPoint will not last as long.
MAC's Technakohl Liner has a better staying ability due to its formulation, but with your watery eyes, it might just stay slightly longer.

Remember that in your tears there are enzymes (lysozyme, lipocalin and lactoferrin), lipids, metabolites and electrolytes. The protein concentration differs between emotional tears and the tears produced by irritants. Tears serve to protect the eye from microbial infections and to wash out irritants.

The liners being not part of your body, tends to react with the tears and be dissolved away.
