More an experimental piece for practicing the following

AK chipping solutions (both types)
Sponge effect
Layering
Vallejo Paint (Rust Colors)

The sides were done using "layering".  The technique consists of the following steps: paint, seal, worn effect, paint, wash off.
For example, base color > seal > worn effect > rust color > wash off > seal > worn effect > grey color > wash off > seal .  You can do the same with the different rust colors, but I was lazy for the most part.  I use 4 different vallejo rust colors and 2 different base color for this built.
The different rust colors were applied using a small piece of sponge.  I didn't use layering for the wheels and you can see the effect is slightly different.
The "worn effect" seems to give a grainier look, whereas the "heavy chipping" the paint just flake off.

Sorry ah war axe gor....don't know how to type in chinese.  Maybe jaffelam - hing can translate

BTW the only part I used the worn effect was the belly and rear deck

Thanks siusiuhong-hing

"層疊法包括以下程序：上色，上保護漆（噴髮膠定消光油？），刮脫，洗塗"
actually is
層疊法包括以下程序：上色，上消光油, 上AK Worn Effect,上Rust色，刮脫，上保消光油
If you do not apply 消光油 there is a good chance the base color will get rub off

A few shots of the model when I first gave it a try
It was done using simply Vallejo Paint and Heavy Chipping
I ended up washing all the paint off
