Fantail "aztecing" for "J" colored panels.

These panels will be overshot with a 50/50 mix of Revell grey and light grey enamel so slightly darker then the main hull color.

Random patterns for the most part. They will be muted once the "J" mix is on:

I added aztecing/shading in chalk for the lower saucer "J" colored panels on either side of the secondary hull.

They will get an overshot of medium light grey but will be be visible underneath:

Aztecing continues on fantail underside panels. The blue tape stretches and conforms to curves so great for curvy masking:

Ventral saucer, fantail, and nacelle surface aztecing {?) chalk sealed with Dullcote clear matte lacquer.

Next I'll work on the secondary hull and the dorsal fantail surfaces.

Then I'll airbrush a thin layer of the basecoat over all the panels and any areas I have  to touch up after closer inspection:

Flash photo. Ventral fantail center panels chalked and sealed with Dullcote. The lacquer darkens the panels so you can really see the pattern.

The pattern was done by blotting the grey pastel powder randomly over the surface before a gentle rubbing.

It looks close to the photos I've seen of the studio model.

I will airbrush over this with the 50/50 mix which should look nice with the pattern barely visible underneath:
