The Hyaku Shiki has been one of my favorite designs ever since
I got into Gundam models, back when Zeta Gundam was new. I built
this same kit years ago, and never could figure out a way to get
the gold finish I wanted. This is the first MS I built after a
12 year break from Gundam, and I promised myself I'd have a proper
gold Shiki this time! After a lot of fiddling with different materials,
I decided to go with metal foil, a time consuming but very satisfying
task.
The kit itself is quite nice, one of the better models from those
days. I was mad when Bandai announced the release of the (already
gold) master grade kit after I finished this, but felt better
when I saw the new kit. I think the proportions, particularly
the head, are much better on the original model.

Construction
I wasn't planning on getting sucked back into Gundam models when
I started this (ha!), I just wanted a nice looking Shiki. So I
didn't do much modification to the kit. The only changes I made
were replacing the kit supplied power cables with new ones made
from slices of plastic tubing (cut from inside ballpoint pens!)
threaded over wire, and scratchbuilding fins for the back of the
legs. I have yet to attach these (sorry, no pictures). ;P

Painting
The gold foil doesn't stick well enough to survive masking, so
I did all of the painting first. The feet were sprayed with Testors
dark red enamel, and the chest and backpack with Testors dark
sea blue (which has a slightly greenish tint), and mechanical
parts with a dark gray mix. At the time, I didn't have a working
airbrush, so I bought one of those cheap $10 Testors airbrushes,
which is really just a spraygun. It did the job, but I never used
it again, it's a piece of crap. I tried to do some shading on
the blue and gray parts, but the spray pattern is just too large
and innacurate. I managed to get a little bit of a shading affect
using pastel chalks, ground on sandpaper and applied with a paintbrush.

Gold!
Nothing looks more like gold than gold! Ok, well, it's probably
aluminum or something, but it's metal. I toyed with the idea of
using Bare Metal Foil (foil that comes on a sheet like a sticker,
with adhesive already on the back), but haven't had much luck
with it in the past. It's very difficult to cut without tearing
unless your knife is super duper brand new, and is pretty expensive.
I ended up using a gold leafing kit from my local Michaels (a
craft store) to cover the model in gold colored foil.The kit comes
with a lot of foil sheets, a bottle of glue, a burnishing cloth
(useless), and instructions (didn't follow them). The glue seems
to just be thinned white glue, so you could get away with just
buying the foil instead of the whole kit.

Applying the foil
The foil isn't too difficult to apply, but it takes some practice
and patience, it's a delicate process. I practiced on an old Gelgoog
I had laying around.
1. It's best applied in small pieces. I cut pieces
of foil (size depending on where it was to be applied) using a
sharp pair of scissors. Then I held the piece by the corner (touching
the surface as little as possible to avoid fingerprints), and
applied a thin coat of glue using an old brush. The glue was pretty
thick for this purpose, so I thinned it with some water. I also
added a drop of liquid dish soap to break the surface tension
and keep it from beading up.

2. Once the glue had dried (a little blowing helped),
I applied one edge of the foil to the part, overlapping the edge
a little bit to ensure full coverage. Have a q-tip ready in your
other hand, you want to burnish the foil with it instead of letting
it lay down on the piece.
|

|
3. I carefully used the q-tip to apply and smooth
the rest of the foil, starting at one corner and working my way
along the edge. It's easier to avoid wrinkles if you work your
way out from the starting point towards the edge of the foil..
|

|
|
4. Once the whole piece of foil is in place, I
smoothed out any wrinkles using the q-tip, pressing very softly.
I found that burnishing in one direction kept the foil from tearing.
When I goofed, I removed the foil with tape and tried again.
|

5. Here you can see the foil after application
and burnishing (I didn't bother doing the wrinkly edge, compound
curves can get difficult). It's ok to overlap a little bit, the
seams nearly disappear. Any extra foil was trimmed with a very
sharp knife. I removed the inevitable fingerprints with a little
window cleaner on a q-tip.
I'd think that this foiling technique would be useful
on the Master Grade Shiki, as there are a few seam lines that
need to be covered. I'm not sure how well the foil would match
the gold plating though....

Finishing
The foil is pretty fragile, so I wanted to protect it from scratching
and fingerprints with a clear coat. I decided to go with Future
acrylic floor polish, having read good things about it's smoothness
and clarity in model magazines. I didn't trust that spraygun,
but found that the stuff goes on so thin and smooth that I could
just dip the parts, soak off excess Future with a paper towel,
and let them dry on pieces of sprue. I dipped all the parts (painted
as well as foiled) a few times, moving joints as the Future dried
so they wouldn't get stuck. The finish is pretty durable now,
though the foil still scratches off pretty easily (fixed easily
enough with more foil!).
I painted a few details with enamel paints and a brush (red verniers,
black eyes, etc). I wasn't sure how washes would react with the
Future, so I filled the panel lines with dark brown watercolor
(again, some soap breaks the surface tension), and sealed them
with brushed on future (it's the smoothest brushing stuff I've
ever worked with).
If I had it all to do again, I'd fix some of the articulation
problems, do a better job with the painting, and maybe try clear
paints over Alclad Chrome laquer instead of the foil. I might
also try doing some shading with clear Smoke on the gold parts
someday. But I'm very satisfied with the result, I kind of like
the unevenness of the foil finish, it ads some depth and looks
superdooper shiny.
