Attitude: Resisting the Fiddly

Perhaps it’s the same phenomenon I was discussing last time, a mental blockage that keeps you from either seeing a solution or, just as importantly, implementing it.

I began building a Hasegawa Kyofu Rex seaplane a week or two back, a project I’ve wanted to do for ages and finally found an excuse to as another test subject for trying out those acrylic topcoats. The model fell together like a dream, there are only 37 parts in the plane and a few more in the handling trolly (the German would be dockwagon). The acrylics are all lined up and ready to go, the only obstacle was masking the canopy. Eduard make a set for this kit’s bigger brother, Tamiya’s 1:48 scale equivalent, but for the one-piece canopy of the little guy I was on my own.

Well, slivers of tape must be coaxed into place with fine tools, obviously. But it took me a week or so to commit to the task. I felt like Sgt. Pinback being told it was time to feed the alien, in Dark Star… “Ohhhhh, I don’t wanna do that… I have to do everything ‘round here…” Maybe it’s my deteriorating eyesight, or persistent memories of being frustrated by such tasks before, but it took resurrecting that Corsair a few days ago to get me to the job. Eduard makes Corsair masks but it would be weeks before I could get hold of them and they cost money, a few slivers of tape are immediate and essentially cost nothing.



So, the mind sees the necessity, the heart deals with the angst, and the hands and eyes do the job. A couple of hours work spread out through the whole day so there’s no chance to go stale on the task, and I had both canopies outlined. From there it’s easy enough to backfill the areas with tape. One concession to the approach is that it’s obliged to be a two-part finishing process: main struts will be painted, fine secondaries, simply too small or intersecting in complex ways with the others, will be slivers of decal, which will be made from clear sheet at the painting stage.

The pre-cut masks are so convenient you forget grass-roots techniques like these. I’ve not made slivers of decal for canopy struts in 15 years, so it’ll be an interesting experiment to see how they work – or don’t. If they don’t, I’ll figure out some other solution.

Product Review: Tamiya Masking Tape

I remember building Revell's prototype F-16 when I was a kid, in the early 1970s, the one painted up in red, white and blue. The kit was molded in white so I let the white areas be raw plastic, and masked the hard-edge red and blue. I used cellotape, which over raw plastic had nothing to pull up and gave razor-sharp demarcations. I was very impressed with the edge work, less so with the finish of flat enamels slathered on thickly with a brush, and which somehow managed to migrate under the tape where it crossed detail.

Not long afterward I tackled Monogram's B-52D, painting the whole thing with a brush in Humbrol enamels. The white underside took coat after coat and must have looked like it had been done with a roller... Due to the size I used automotive masking tape and of course discovered the necessity of de-gluing the back. Even over well-cured, thick enamel the tape had a de-surfacing effect that was not attractive. I had planned to mask and paint the walkway stripes over the NMF but after early experiments abandoned the idea. Somehow paint would always migrate under, no matter how well-burnished the tape edge seemed to be...

I used to think joint dressing was the biggest drag in the hobby, but since the advent of both cyanoacrylate glue and better-engineered kits joints have become simply a part of the process, not the disfiguring headache they once were, and the necessity of masking the paintjob has rather moved to the fore as the most time-consuming task in reaching a really good result.

Household/automotive paper tape is not designed for delicate paints and you need to seriously de-glue it to stand a chance. Scotch brand invisible mending tape is not very sticky and produces a very sharp edge. The problem with these two is they are not very flexible, they don't deform easily around corners. In the US there is the blue 'painters' tape,' but I'm not aware of it (or an equivalent) in Australia. To be fair, I've not checked out hardware stores for the item, but there's not much point when you have an item like Tamiya tape in the tool draw.

If there was a perfect product for this application, I'd have to say Tamiya have nailed it. Their tape is low-tack, burnishes down tight, deforms readily, and peels off clean. I have yet to have it pull up sprayed acrylics or enamels over any properly prepared surface (the only time I had it take paint off right through to the plastic was attributable to a deposit left on the surface of the model by the cleaning agent I had used to degrease it). The tape is also essentially re-usable, I have used the same pieces of tape on multiple projects, simply by transferring them to another plastic surface where they can stick for weeks or months and again peel off cleanly.

The tape comes in a variety of widths from narrow to broad so you have the option of curving lines or bulk coverage. I usually put a strip down on my cutting mat and slice it up with a razor knife and steel rule into ultra-narrow pieces or shapes as the job calls for. The dispenser rolls are a good idea, too.

The FW 190 I have on the bench at the moment was masked in both hard and soft contexts. The unit markings featured yellow rudder, cowl and fuselage bands, and rather than go with the kit decals for these items I sprayed them at the same time as the rudder. After overnight curing I masked them with strips of Tamiya tape and carried on with the rest of the paintjob. Several days went by, then I removed the hard masks and discovered perfectly sharp edges, and perfect protection of the underlying paint from later applications.

The big resin Beta-1 bomber featured in the last couple of posts was also fully masked with Tamiya tape, a long and complex operation, but one which went off essentially without a hitch. The colour demarcations are as tight and sharp as you could possibly wish for, with absolutely no paint bleed-under or de-surfacing on removal.

Tamiya tape is an indispensable tool in my kit, and I recommend it without reservation.
