Basic Weathering Techniques

Found this japanese website with a tutorial on weathering your gunpla.
The pictures seemed to give quite a good depiction but I can't understand a single word of its explaination.
So I used google translator to translate the pages.

Lesson 1: Pre-shading
Lesson 2: Simulating Mud
Lesson 3: Worn Out Surfaces
Lesson 4: Drybrushing 1
Lesson 5: Drybrushing 2
Lesson 6: Battle Damage
Lesson 7: Rusting

I dare you to not laugh at the translated text.
