Thanks Mucker. It's been a fun build in spite of the few self induced hurdles I created for myself.
I was able to get the two tiny decals over those ducts without too much difficulty last night. I also drilled out the gun barrels and they're all painted and ready to go. I'm going to do just a tiny bit of touch up with some gloss black in a few small spots where one of the tulip decals had broken apart.
I'm going to do one more coat of future to seal everything in. I'd like to try doing a few oil, gas and hydraulic fluid leaks, spray some light exhaust stains then flat coat it.
