For what it's worth, I wouldnt have painted on the deicer boots yet, those should be put on after paint is done.
The interior, your goona have a hard time with getting all of the interior in because your gonna have to scrape paint away from anything that will be glued. I use elmers glue, brushed onto where all the joins are gonna be, then spray the interior color, after all is dry, peel out the elmers glue.
Also, when posting pics from photobucket, just copy and paste the IMG code.
How does the fit look so far of all the major joins? Wings and fuselage.
And preshading is easy, I'm gonna assume your airbrushing so... Get all of you major assembly work done, windows and canopies on, masked etc. Spray the canpoy framing interior green (this next part is optional but its what I do, after the canopy is sprayed the interior color, I spray the entire exterior with aluminum, just one good even coat. Let sit a few hours) Next, put flat black in the airbrush, the just simply spray all the panel lines black. Then your read for the olive drab and neutral gray.
