I referred to the Mig Jimenez blog as well.
I also looked at old copies of the Japanese magazine Armour Modeling.
I used a very fine brush (00) and Testers modeling master enamels, because they dry slower.

I build up in thin layers in this order:

-Dunkelgelg-(lightened with white) to show wear around edges of chipped areas and over areas of green and red brown
-Rust- also resembles the German primer color
-a mix of Gun Metal and rust -to make the exposed steel color
-Steel- to drybrush highlights

Some important factors to consider:

-practice-Spray paint some scrap sprues or unused parts and practice on them first.
-patients-Do one area of the tank at a time and don't over do it. (restraint is hard)
-planning-Think about how the tank was used and what high traffic areas would be.
For example, I imagined how the commander would climb up the ladder and step on top of the turret and climb in to the cupola.
-Avoid creating patterns, or chipping at regular intervals, the chipping process would occur organically or more randomly

I am try to load a picture but I keep getting an error.
Yea RCU!
If you click on my name and go to my profile and click on Gallery, I have some pics of my Panther, which was my first real attempt at chipping.
I did not try it on my Pershing.
