Applying Tissue for a Seamless
First, it is not necessary to pre-coat the frame with dope or white glue before applying the glue stick. Just sand the frame smooth, and apply a light coat of the UHU evenly. For those interested in wing loading, this saves a few grams. It may also be the reason that my tissue has never lost it's hold in damp weather, since the glue is directly on the balsa, and not on a thin coating of dope.
Secondly, the glue stick is odorless, so gone are the days of saturating the house with the smell of dope. Also, there is no rush with using the glue stick. Once it's on the frame, you can walk away and come back hours or even days later if you need to. The glue is easily reactivated through the tissue with isopropyl rubbing alcohol.
I apply the tissue in the standard way, tugging softly as I move down the fuselage for example, floating on some alcohol through the tissue with a small brush. The alcohol is tissue friendly, and doesn't break apart the fibers as quickly as water would if you were using white glue. Still, you need to be gentle. The glue stick allows you to lift and reposition the tissue as often as you'd like, so again the pace is less hectic. For me this is very important, because I like to think of the covering process as a relaxing experience, and not one of 'spinning plates' as on the old Ed Sullivan Show.
When overlapping the tissue on a frame, I float some alcohol
on the seam and softly rub it in with my finger. This appears to melt the seam
together, creating a soft and nearly invisible overlap.
Generally I pre-shrink and pre-color my tissue on a frame, using acrylic enamels and an air-brush. I also try to apply any markings or numbers with an air-brush before I attach the tissue to the model. This makes for a lighter and cleaner appearance. However, occasionally markings are attached with colored tissue and a glue stick, again using alcohol to reactivate and seal.
Finally, after the tissue is shrunk on the model's frame with
alcohol or water, I 'dust' the model with either
Krylon matte or crystal clear (gloss).
This seals the tissue and more importantly has proven to prevent it's continual
shrinkage, which often turns our beautiful, perfectly trimmed models into
Post Script: I usually try to add some opacity to the tissue, even if it's yellow tissue, as on the Cessna C-38. I feel it helps keep the look consistent when you cover not only the frame but also sheet balsa.
That look where the sheeted areas are far brighter or a different texture etc than the framed areas always makes the model look odd. So again, spraying the tissue yellow in this case, with a bit of white added to the yellow, seems to make the surfaces closer together in color.
But it's a fine line of course. You can go overboard with the
spray, and suddenly it's looking and weighing like a dope job over silk instead
of tissue. I like to come in somewhere between Pres Bruning and Chris Parent.
