Wow! talk about being overwhelmed by response! :-)
Butz:
The special tail markings for the 6 Sqn. anniversary bird are on the kit decal sheet though the boxtop has a photo of the other kit decal option of the first RAAF "G" model called "Boneyard Wrangler"
As for the painting and panel lines: The painting guide calls for overall Gunship Grey, but I figured in the rapid fading that would occur under the bright Australian sun and used Neutral Grey instead. I used paints from the Model Master Acryl range.
Now the panel lines: I was pleasantly surprized by how well they turned out as I tried a different method than the usual wash. I emptied out the graphite dust from my drafting pencil sharpener into a plastic margarine container and found a cheap, wide and soft paintbrush (and I mean REAL soft). I held the plane over the container while I picked up liberal amounts of dust with the brush and softly fanned it onto the model. After it was dusted, I took a damp paper towel and gently swabbed the surface of the plane. The dust stuck nicely in all the panel lines and came cleanly away from the general surface area.
A couple of coats of Testors Dullcoat from a rattle can sealed it all in.
I got that idea after watching a cop dust for fingerprints on a documentary about forensic investigations on T.V. the night before. I decided to give it a go. I think it will be my standard panel line treatment from now on.
The only things I'd do different is to really give the surface a good cleaning before applying the method (I had to get rid of a couple of latent fingerprints before clearcoating) and to wear surgical gloves while doing it.
Thanks for all the great comments, keep em' coming!
