Cut down costs?

Some of you probably work on several kits simultaneously, do you?
I think try this too. There's a main reason:
when use airbrush i'm wasting away too much paint (especially for small parts )
That's idea came to my mind: gather together pieces from many kits with the same color and paint it in one time with airbrush. So it will demand less paint than do it separately. What do yuo think?
Now I have 3 kits almost untouched in my shelf:
Alpina B7 turbo
Ferrari Dino
Mercedes CLK DTM
"almost" becouse I already completed engine for Alpina

in process:
Porsche 911GT3: waiting for final coat of yellow
Porsche 959: body preparation for priming; interior almost complete

No!

You need to 'feel the mood' for a kit!

Sleep it, breathe it! Imagine the real car, research it! Get enthused over it!

You simply can't do that with more than one kit! It becomes more of a factory!
Ita takes the joy away, which, afterall, is why we do this hobby!

you're right about "feel the mood"
I can't get pics of real Alpina B7 interior
