Since my last built I'm really interested into the whole whitewash thing. I did several experiments and want to share my results with you:
- I found out that the most important factors are amount of HS and amount of the top color layer.
- More HS means bigger chips
- I did several test and it seems that the longer you leave the top layer, the harder it will be to remove.
- The surface has a slight impact as well, on glossy surfaces the paint is easier to remove.
- The difference between a matt or semi glossy surface is minor
Here some pictures:
A couple of styrene shets were primed with black primer from GW:

Lifecolor grey as base coat applied:

Hairspray applied, for better control I spray the HS with my airbrush:

Top layer of Tamiya white, thinned with water.

You can see clearly the difference between the samples.
Less HS means smaller chips (good suited for rust, on some areas effect similar to dry brushing)
