G'day.
I've put the main personal markings on this beast. Various comments I'd read had said Roden decals were difficult to work with, sometimes shattering when moistened or removed from the backing paper, inconsistent and immune to decal setting and solvent agents. So I experimented with some spare markings, using a brew mug (tea/coffee mug) as a "perfect surface". (The missus asked me why I was "numbering the mugs, Dear?". When I explained, all she was "Oh", kissed me on the top of the head and walked away. Women.....) .
From my experiments, I found that:
1. They are immune to MicroSol, MicroSet and Mr Mark Softener.
2. Unless you use near-boiling water, they are stiff and very brittle.
3. They are inconsistent- two decals placed side-by side will act differently, with one silvering and the other not.

4. Once they're down, don't move them much or they will tear (see the first "12" below).
5. They aren't opaque, with no white backing behind the prints, so some decal details change colour on different parts of a decal. and
6. The propeller logos have been simplified to uselessness.

7. They're slightly out of register.
I also had a problem with one part of the sheet. The clear decal had frosted on a couple of markings, one being the starboard side "Hat into the Ring", and part of the decal stuck and wouldn't separate from the backing. While the frosting doesn't show up much on the photo below, it is quite apparent on the model. I'll have to paint over this to get it sorted.

In the end I used the following method to apply them, with pretty good results:
1. Use near boiling water, changing it after every couple of decals. The water doesn't have to cool down much before the dcals stiffen and become brittle.
2. I used One Go (Aussie Pledge/Future/Klear) as a wetting agent, using a hot-water-dampened hankie to press the decal down and remove air bubbles. The One Go wet the surface and pulled the decal down as it dried, while the hot water kept the decal soft enough to conform to the details.


I have, however, ordered the Super Scale decals for LT Roosevelt's aircraft. The sheet will supply new national roundels (the kit ones just aren't up to scratch), better prop logos and some extra stencils.
Once they get here, I'll finish decalling and then do a little bit of weathering. All the loops and turnbuckles are installed, ready for rigging and the struts have been drilled and .25mm copper wire glued in as pins. I've enjoyed this build- after the J.1 it was just what I needed to keep the interest levels up. Next up- a 1/48 Crusader Mk I (yes, a tank! A mate sent the kit to me to try), then the WNW Tripe.
Cheers.
