The weathering is only maybe a third of the way done,( I still need to post pics of weathering models* on your thread and I try today).
What weathering you do see is from everytime that I used silver in the cockpit, I'd do a little to the plane.

I'm no expert, just copying techniques from scale plastic models.*

Today I'll take a few pics to show detail of the canopy rails and more of how I got it to work.
Then I'm pulling my canopy for painting and finishing my cockpit interior.
