That is really sweet looking, cnq!
Love the camo!
My advice for the silvering decals is a "try at your own risk" solution, but it does work. You can try using Testors liquid cement.
The problem is that it will dissolve the carrier film, so you really want to take it slow and easy. One quick swipe and let it sit for 10-20 minutes.
Repeat as needed.
If you get too agressive the LC can smear or distort the decals.
Trust me on that. I've been using this trick for a long time. Decal repair becomes part of the process when you get impatient. But not all decals react the same and Academy decals are pretty resilient.
You should be safe if you decide to give it a try.
