yeah buddy...
I like the airbrush idea. I am fairly decent at painting cars with my HVLP rig, but this is a different scale. Blending is always the challenge.
The main issue is not to make it "showroom" but to protect and seal the exposed areas.
I really like the "clean it up first" then paint match. That will also allow it to take into account the aging of the pigments.
Nice, thanks!
