CG,
Here's my $0.02...
1) For the cockpit masking, you can go the masking tape or post-it note route. Or if you can get a hold of it, this is what I used, PARAFILM M - http://www.clubhyper.com/reference/usin ... lmda_1.htm
If you're using enamel paints, then they have a reputation of seeping under masks. I only use Acrylic paints, as they don't do this.
As for detailing the cockpit, forget it! It's only 1/72 scale and when the canopy is on you can't see much inside.
2) For decaling, I followed Brett Green (off Hyperscale.com) advice of this technique...
a) Spray entire model with GLOSS varnish.
Then get some thinned down dark brown/black and paint all the panel lines. Don't forget to thin it down even further when doing underside, as it's usually a lighter colour.
c) Get hold of some MICROSET - http://www.chimneyvilledecals.com/mideseso1.html to brush onto area where decal goes. Dunk the decal for only 5 seconds then take it out of water and let it soak out of the water. Then place decal on A/C
d) Once all decals are dry, get some MICROSOL - http://www.chimneyvilledecals.com/mideseso.html and brush over briefly every decal, wait till every decal has dried, then repeat process. I did at least about 10 coats. It sort of melts the decal so it conforms to the model and the rivets can come through and it looks like a real paint job and not some ugly stickers.
e) When done, do your paint chips with a silver pencil then spray entire model with MATT varnish.
I haven't tried making the aerials.
