Re: Grubbing up a model
(sorry if this is too late, BUT)
Yeah, definately do NOT use charcoal; way too messy and wont really get the result you would like. If you insist on using graphite-type things, take a #2 pencil and scribble as hard as you can (dont break it!) on a piece of paper. This will cause little chips of graphite to rub off, resulting in perfect "grub". Dip your finger into it and smear it where you would like on the model. But again, this may have a hard time adhering due to the glossy finish of most models as described by Compass.
My perfered method as follows: Get some acrylic paint (any type should work), black or your choice of "grub" and dilute it with some water on a piece of paper (or any pallete you like). Make sure you have more paint than water (I like 65% paint and 35% water). Now, if you want panel lines on aircraft, take the paint/water and literally paint it ALL OVER the wing, etc. Don't be afraid of ruining the model, cause you wont! Now the fast part. Get a rag/paper towel and wipe off all of the excess paint/water almost immedeatly. Try not to apply too much downward pressure, as this will wipe up the paint/water in the panel lines; apply side-to-side pressure, if that makes any sense.
NOW, if you want dirty areas like engine exhaust fumes area, APU's, etc. this is what I do. Use the same ammount of paint/water mixture (it really varies on what you like though, you must practice on something crappy first!) and dab a big drop of that stuff on the designated "dirty" area. Now, let that sit for, say, three whole seconds. Now comes the fun part! Take rag/paper towel and start dabbing the spot and around it. This should produce the dirty as heck look.
Remember, if you mess up anywhere, you can always get some alcohol and just clean it up.
I have never tried this on a pre-maid model, so I can not tell if these methods will work 100%, but they should produce some positive outcome.
