I just went back and read this journal again. You have done some great work here. I have experienced problems in the past with silver paint and also lost a lot of work when tape removed a good portion of the sprayed on red / white tail stripes on an AMT 1/48 scale A-20 Havoc I have. This plane has been setting on the shelf of doom for at least 7 years now. I simply got so frustrated I walked away from it and have yet to go back and finish it up. It had full intentions of covering it in "Bare Metal Foil", to replicate a natural metal finish that was highly polished... and I eventually will some day.
Here's what I'm getting to: You might be able to use some bare metal foil for the leading edges where the de icing boots were removed. They make a color called "Matt Aluminum" and you can alter the shine by spraying on Dull coat or something similar. The more flat coats you apply, the less the intensity of the shine.
Another option to help you with masking, is you can simply wrap your model in household aluminum foil. Tape it along the edges and as long as there are no pinholes or leaks, you will be good to go.
I have used this method and it works fine. Hope this helps.
Your OD Green paint work looks splendid... 🙂
