Storage (Cab Transkits & Large Castings)
When you purchase any resin transkit, or any of the larger multi part kits, it will have been carefully packed to ensure both safe storage & safe transit. It is vitally important that if you open your kit & then decide to re-package it & store it for later use that you follow these guidelines;-
- Never wrap a cab shell or large thin casting tightly in bubble wrap, only wrap it loosely.
- Ensure that no other item or piece of packaging puts pressure, however light, on the cab roof. Resin is pressure sensitive & will change shape over time if pressure is applied.
- Never store a resin kit in a loft or roof space. These areas can become incredibly hot in summertime. Remember resin is heat sensitive & will rapidly change shape if overheated. This problem is compounded if the item is tightly wrapped or has pressure applied from packaging or other boxes.
- Never store resin in a cardboard box in damp conditions. The packaging chips may be the bio-degradable type & will rot if wet. The box may collapse under the weight of other boxes stored on top. You may have decals in the box with the kit.
- And remember, once you have built your model DO NOT store it under any of the conditions mentioned above, DO NOT display it in directly sunlight (especially in a glass display case) DO NOT display the model above fireplaces or heating radiators.
It is certainly no secret
that working with resin can be more difficult than using straightforward
plastic kit parts. But with care & a little patience a far more
unique & interesting model can be the end result. Always ensure
that resin parts are thoroughly cleaned of any silicone release agent
by gently scrubbing all areas with a rich solution of warm (not too
hot) soapy water (an old tooth brush with neat washing up liquid is
ideal for this purpose) & allowed to dry naturally. Ordinary white
spirit is also useful for removing any release agent. Cellulose thinners
should NOT be used. Lightly flatting parts back with a fine wet`n`dry
paper will also help prevent any potential `fisheye` paint problems
caused by silicone contamination. Flatting also provides a much better
paint finish & a good key for primers.
Another very useful tip for
cleaning & flatting resin (or plastic for that matter) is to lightly
scrub the parts with Vim or Ajax bathroom scouring powder. It must be
the powder form though rather than the cream version. Simply wet the
model, sprinkle on the Ajax & scrub with an old tooth brush, rinse
under the tap. The result is a clean matt finish surface ready to accept
a primer.[top]
Reshaping
Resin is very heat sensitive,
only use very hot water or a hair dryer when you need to reshape a distorted
part. Slight distortion of resin parts when demoulding or during storage
is quite common & can easily be corrected by immersing the distorted
part in hot water for a few seconds, re-shaping as required by hand
& then immersing in cold water to `fix` the new shape. The hotter
the water & the thinner the part the quicker a part will soften,
bear this in mind on thin items such as wings or cab panels. [top]
Gluing
Resin can be sanded, sawn,
drilled, filled & filed as required but a face mask should always
be worn during these operations, avoid breathing in resin dust. Superglue
or 5 minute epoxy resin should be used when attaching resin to resin,
metal or plastic. Ordinary liquid poly cements will not work with resin
or white metal components. It is also a good idea to lightly sand all
mating surfaces when attaching resin to other resin, metal or plastic
parts. When working with photoetched metal parts use 5 minute epoxy
rather than superglue if possible as `smoke marks` can often occur.

Painting Resin
Resin is a very versatile
modelling medium that will accept any form of paint topcoat but it is
vital to use the correct primer & undercoat to begin with. For best
results on both resin & plastic parts use an auto acrylic primer
first.
A) ENAMELS. Remember an enamel
based primer will only accept an enamel topcoat....anything else will
attack the enamel primer. Likewise if you apply an auto acrylic or a
cellulose finish over an enamel topcoat finish this will also `pickle`
the enamel. It is quite safe however to apply enamel on top of any auto
acrylic or cellulose paint. When applying a second coat of a thinned
enamel by airbrush or spray gun this must be done either after the first
coat is not only dry but `hard`, this can take a week......or......it
must be done within 10 minutes of applying the first coat. The reason
for this is that the thinners in the second coat will often attack &
wrinkle (known as pickling) the skin that has started to form on the
first coat.
B) CELLULOSE. Cellulose primer will not attach itself to plastic
or resin surfaces. It may look like it has gone on OK but all you have
created is an egg shell over the model. Although you can apply any form
of paint over a cellulose primer there is a good chance it will crack
& break away from the model in flakes right down to the bare plastic
or resin, especially when removing any masking tape. If you must use
a cellulose top coat then it can only be safely applied over an auto
acrylic primer. Auto acrylics & enamels are quite safe to apply
on top of a cellulose surface.
C) AUTO ACRYLICS. Not to be confused with water based acrylics such
as those made by Tamiya. The main supplier for good auto acrylic in
the UK is Hycote. The Halfords own brand of auto acrylic is also made
by Hycote. Grey primer is recommended for darker colours such as a dark
green, blue or black. Lighter colours benefit from the use of white
primer, especially red or yellow. White primer has the ability of keeping
the top coats `bright` whereas a grey primer used under a red will often
affect the end colour result. Cellulose or enamels can be applied over
auto acrylic quite safely. Try to stay away from red primer & remember
that metallics will always require at least one coat of laquer to bring out the best
in the paint.
D) TWIN PACKS & LAQUERS. A twin pack is a paint that requires
a special thinner plus a measured amount of hardener to be added to
the paint to make it cure. These are largely for professional auto use
& require special breathing apparatus. Stay away from twin packs
unless you have no choice, you can quite often recognise a twin pack
paint as it smells strongly of pear drops. The use of laquers to improve
a gloss finish is largely up to the individual. In my humble opinion
Humbrol clear gloss varnish No35 is about the best available for general
modelling use. The satin varnish No135 is also good for curtains where
a gloss is not required. These are both safe to apply over any paint
finish & any brand of decals. Other laquers however, especially
aerosols, may well pickle & ruin your decals, this is because decal
inks are treated with a clear varnish coat during production. Some decals
use a cellulose varnish & some (all KFS decals) an enamel varnish. If in doubt use
an enamel varnish such as Humbrol. [top]
Decal and Weathering Tips
 |
Decals
Tip: When fitting any decals & especially fine decals such
as KFS pinstriping use a little washing up liquid in your decal
water. This really does make a difference , the decals will slide
a lot easier & be less prone to sticking & curling under.
In the average size saucer you only need 2-3 drops that's all. This
also works for much larger area decals such as on trailer decal
sets. It allows the decal to be moved around for longer & makes
the removal of water from under the decal a lot easier. Large decals
should always be lacquered over to prevent cracking later on. Allow
at least a week for drying before lacquering [top] |
| Exhaust
Tip: To produce curved exhaust stack ends simply take a piece
of scrap sprue close to the inside diameter of the pipe & insert
this into the end of the aluminium pipe. Gently tease the pipe between
the thumb & first finger to about 45 degrees. Do not make the
bend too sharp as this will kink the pipe. Once curved, twist out
the sprue & cut the pipe in line with the upright using a razor
saw. Trim up the pipe with a scalpel & wet-n-dry, polish to
a high shine with metal polish. [top] |

Weathering
Tip: Subtle dry brushing can often improve the look of a model &
take away the toy like appearance given by too glossy a paint job. It
will always improve the look of high detail areas such as engines,suspension,
axles & rivet detail on chassis`s. See below for the method. [top]
Dry brushing: Use a matt aluminium or pale
grey for highlighting. Stir the paint well & apply just a little
to a piece of scrap card. Take quite a stiff brush (an oil paint brush
is ideal or even an old tooth brush) & just touch the end of the
bristles into the paint. Now wipe away as much of the paint as you can
from the bristles using a rag or tissue. Now brush the detail area on
the model quite briskly with the virtually dry brush. A tiny amount
of paint will be deposited on to the high points of the model, giving
just enough colour change to highlight the detail parts. Practice makes
perfect but remember, a tiny amount of paint goes a long long way. [top]
Etch Detail Tip: To highlight half etched
detail in photoetched parts. Just flood coat the area to be coloured
with the paint colour of your choice. When the paint is dry but not
hard lay the part face down on a piece of clean white paper (back of
an old photograph is perfect) dampened with white spirit. Now rub the
part around in a circular motion to remove the paint from the raised
areas. This now leaves chromed raised areas & coloured half etch
areas. See Western Star mudflaps in the top picture for an example.
