We live in a pre-packaged age, an age of immediacy.
Labour-saving devices are expected, we whine if we don’t get them. The hobby is
no different, speed and ease are virtues – I have certainly grumbled enough
about kits that presented more of a challenge than I had the stomach for at any
particular moment.
The painting mask is one of those modern conveniences, a
go-to product that cuts the elbow grease (well, wear on eyesight, patience and
dexterity) that old-fashioned masking called for. I posted not too far back on
the thought that traditional masking was a dying art; I still do it from time
to time, but if a pre-cut set is available for a model I’ll probably buy it,
just to streamline the procedure.
But, and this is the big but, what if that process goes
wrong?
I recently found myself in that situation, the mask set went
on fine but the paint had so little adhesion to the canopy that it simply
flaked off as the masks were removed. Much grumbling and cussing ensued, of
course, and scratching of head and thinking back. Did I want to remove the
paint, clean the transparencies and completely re-mask by hand, then paint
again? A Stuka? You’d have to be joking! So… what?
I remembered a technique I read about when I was a kid and
had in fact used in the ‘80s, experimentally. Frustrated with daggy-looking
canopy struts and realising my dexterity with a brush was not going to improve,
I had tried the “decal method.”
The theory is simple enough, paint a piece of decal paper
with the inside colour, then the outside colour, cut with a razor knife to the
required width and apply as per normal… this was before the day of mask sets or
commercial clear film (well, Microscale was doing it, but that hallowed firm
had not yet quite become the daily resource for me it would later).
It worked sort of okay at the time, I guess (I remember
decal adhesion being a big issue), but I never did it extensively, my most
ambitious use of it being the gridded canopy supports of the Revell 1:32nd
scale Bell X-1, about twenty years ago, which I finished with pre-printed black
decal strips from a Queensland firm call PJ’s, if memory serves. The need for
the technique receded into the dusty attic of my memory with the coming of
dye-cut masks and I never thought about it again. But faced with the failure of
the modern method (I’m unsure why, maybe finger grease got on the canopy as it
was being masked and resulted in a barrier to paint adhesion), the old trick
resurfaced in my memory.
After moving house I could not find my clear decal film, so
mail ordered some from interstate, Microscale’s TF-0 Clear Trimfilm. This is
the good stuff, from the big brand. I sprayed RLM 02 for the interior and RLM
70 for the exterior (Model Master Acryls), then brushed Liquid Decal Film
overall (it levels perfectly, brush strokes are virtually nonexistent), and
used my Chopper II plastic guillotine to cut super-fine strips. Then, with an
air of experimentation, I went through the decal process.
Well, blow me down if it didn’t actually work!
Okay, the strips were perhaps a fraction wider than they
should have been, but we are talking about fractions of a millimetre,
translating into maybe a scale centimetre, and it would take a near-terminal
rivet counter to complain about that. I did a test strip on a piece of plastic
and it went on fine, then fell off with zero-adhesion, which caused some
anxious moments, but MicroSol solution got it to lie down properly and it stuck
thereafter. So, emboldened, I tackled the job and in a relatively short time
had a completed section.
The strips are absolutely clean and sharp, and create the
necessary pattern in a way that is pleasing to the eye. Certainly where
straight lines are concerned, the technique seems to be a winner, to the extent
that I would consider going with it from scratch, depending on the subject.
Of course, sealing the strips is another matter – spraying
my usual satin would diminish the transparency of the canopy, and dipping in
Future would create a gloss on the struts that did not match the rest of the
aircraft. If they are not sealed it may well be a case of them drying out and
simply flaking off in time, so there is a compromise of some sort to be made.
I’ll observe them over time and see how they behave: certainly unsealed
Trimfilm strips used on another model about seven years ago are in poor shape
now and demanding a rework.
The truth is, some strips grabbed tight, others did not,
subsequent handling knocked off one or two which had to be replaced, so the
process was not without frustration. Also a number of strips broke up after
soaking, so at least two coats of
Liquid Decal Film are indicated.
Was it perfect? No, nothing is. Does it pass muster? Yes,
and that’s probably the biggest factor.
We have become very particular about the details of our models,
competing with ourselves for ever-greater refinement, and we take poorly when
anything gets in the way of that; it’s good to know, however, that some of the
traditional fixes still work.
