When modelling, I generally like my finished project looking like it really has been out in the field, bruised and war-torn.
Scuffed and mud spattered AFVs and jets streaked with oil, grime and exhaust staining. Weathering my model is one of my favoured parts of the modelling process.
Japanese WW2 aircraft are one of my favorite themes, too - and just great for weathering. Whatever paints Mitsubishi, Nakajima and Co' used on their aircraft, it didn't seem to hold up well to the heat and humidity of SE Asia.
Towards the end of the war some of these Jap' aircraft really did look pretty shabby.
I'm currently going through a PTO phase, and I wanted to try out some paint chipping effects on my latest build - a A6M5 Mitsubishi Zero.
I'd heard about the 'hairspray technique', but being a die-hard hairy stick user, I believe this technique is for the airbrushers - so, that was out.
An internet search led me to this product:
AK Interactive Heavy Chipping Acrylic Fluid
"Odorless fluid to create heavy chipping effects" it reads on the bottle - great! I bought some.
Now, to abuse this Zero...
Here, we have a 1/72 engine cowling from the nose of my aircraft.
Firstly, we need our base colour, the colour that will be exposed by the chipping. In this case, a natural metal, painted over my primer.
Over this, for added protection - I don't want the base colour coming away with the chipping - a clear matt coat.
After that is completely dry, a coat of AK Interactive Heavy Chipping applied with a brush.
The fluid is thin and clear.
After the piece was completely dry, time to apply the final layer. In this case, for the Zero nose cowling - Humbrol 33 Matt Black Acrylic.
... and left to dry overnight.

And so, now for the 'chipping'. Instructions on the side of the bottle, suggest to 'lightly hydrate' the area you wish to add effects to.
Now using a tool, rub away at the part for the desired effect. I used a cocktail stick and needle file to scratch away at the cowling for a chipped, worn look...

I like it! And with a little more practice - as with most things with this hobby - I imagine some pretty realistic weathering can be achieved.

AK Interactive Heavy Chipping Acrylic Fluid (AK00089) comes in a 35ml bottle, and retails at around £4.99 (as of December 2014) in Ebay stores.
