Most important of all is you're responding well to the injections and getting back to being able to use your hands. Fingers crossed you keep making progress to a full recovery.
I haven't tried paint masks myself yet but it's on the list. I've done a lot of worm camo work and the results are awesome, just so time intensive. Looking forward to seeing the finished cammo work - I'm sure it's going to be topnotch. For the Spitfire, I'm going hard edge as a lot of the builds I've followed and research, shows a hard edge was regularly used. See how it goes.
