After the kit was coated with clear spray, I can start weathering.
I did the weathering using oil paint as usual.
First, I added water, rust and oil stains with black oil paint.
I added same effect as cockpit hatch on side camera housing.
Also I did weathering in the same way on the arms.
I used Tamiya enamel for panel line before clear coat, and add the blurring of oil (Tamiya enamel).
I can use black paint for water or oil blurring, and red or brown is can be used for rust.
After 1st weathring, I added paint chipping.
I use Tamiya Enamel (Neutral gray) for chipping. I use very very fine paint brush and "drew " chipping.
I did silver dry brush on dark gray area at Canon.
also, basic weathering around the cockpit.
I assembled temporarily to check the overall balance.
1st weathering is finished
But I add a little more next.
