I enjoy the whole process.
Busting plastic : opening the box,and unbagging the sprues.
Data collection,grabbing a referance book,with pictures,just to make sure the manufacturer didn't royally screw up.
Assembly,there is no more fun than watching the sprues become depopulated.
ZEN MOMENTS : I enjoy painting roadwheels and assembling track.This is usually an all evening job. There is something zen like,sitting,gluing track,or hand painting the rubber part on one roadwheel of 24 or more.
General painting,since I have a permanent home and setup for my airbrush and paintbooth,it is very easy to set up and go.
And the end,when it is all decalled,and dullcoated,I now take digital pictures to store on line,and send you all to go see. (++) (++)
