Thanks for your replies guys[:I]
The mottle was applied with a synthetic sponge which I cut from a Meguiars polishing pad.
The fella at the local auto store thought I was weird when I walked in and bought 7 different sponges to test out, none of which gave me the scale I wanted (there went $32 bucks I coulda spent elsewhere [:(])
So I went into the shed and tried the polishing pad.
It’s a round pad about 90 millimetres across, and has Meguiars moulded into it on one side.
Turned out to be a winner!!


Application was simple, just used straight acrylic paint, dabbed the sponge in it and blotted it onto some post-its till it was nearly dry, kinda tacky actually, and went to town on the fuselage.
I found it better to let the paint dry on the sponge and just keep adding more paint, then blotting till tacky, then applying as this gave a more ‘refined’ look as the paint built up on itself.
It took 2 or 3 dabs onto the model in one area to get a decent amount of coverage and to make the camo look ‘right’.
As for the LED wiring, in the 3rd picture there are 2 wires poking out from the bottom of the wooden base.
These run up to the landing gear, through the base and into the wheels which I drilled out.
Then they form the brake lines up the struts and into the fuselage.
2xAA batteries power the LED and our housed in a routed out section in the base.
Thanks again for your replies.
Might do another sponged 109 now I know how to do the mottle.
