All this talk of puttying and sanding brings up something I've been meaning
to mention for a while. A well engineered kit (as most Bandai kits are)
requires little if no putty if you glue it together properly. I'm working
on the old 1/100 Type 100 kit, and even though the kit is like 10 years old
(as are the molds, which have deteriorated a bit), I've built the whole
thing without any putty. The trick is careful dry fitting. If the parts
don't fit well, chop off the locator pegs, then sand them on a flat surface
a bit. They should fit nicely now.

Next comes the gluing, which is very important. IMHO, the best glue to use
would be a liquid cement such as Testors (I actually just use a big can of
Methy-Ethyl Keytone from the hardware store, I'll never run out!). This
glue is water thin, and actually melts the plastic just a bit, making for a
nice fit and VERY strong bond. Apply the glue to the mating surfaces of
both parts (it dries VERY quickly, just apply it a few times to soften the
parts a bit) with a small brush. Be really careful when applying the glue,
since it's thin, it will try to run under your fingers, then you get
fingrerprints you have to sand off. Then stick 'em together (unless you're
really quick, they'll barely stick). Then apply a decent drop to the seam
(preferably on the inside of the part), and cappilary action will draw the
cement along the seam. Depending on the plastic, you may need to apply a
couple of drops. After a few seconds, the plastic will soften, then squeeze
the parts a bit, and you'll see a little bit of plastic bubbling up from the
seams. If need be, adjust the fit of the parts while the glue is still
soft. When this dries (I usually try to wait a full 24 hours), you can just
shave/sand off the little bubbled out part, and you've got a perfect seam,
all plastic, no putty (I hate putty)! I haven't built any post ZZ kits, but
even the older ones fit quite well enough for this to work, so I would think
it should work on the newer ones without any difficulty.

Also, I just want to mention that modeling tips are modeling tips, be it
tanks, planes, mecha, whatever. There's TONS of information out there for
modelers, and very little of it is geared toward Gundam modelers. Check out
modeling magazines, books, and websites, even if they aren't about mecha
modeling, you'll be glad you did. Plastic is plastic, and those tank guys
really know how to weather. :)
