Hi wbros - I'm guessing you are after a description of a technique for applying lozenge decals in general? If so, I'll chime in and briefly describe the technique I used on my last model (Eduard Albatros D.III), which was my very first time using Lozenge decals - quite daunting the first time around I must say!! I used Eagle Strike lozenge and rib tapes - I had absolutely no dramas with this brand of lozenge decal and from what I am told the colours are fairly spot on.
The first thing I do is spray the area with a clear gloss coat, this helps the decals adhere much better. I then cut the decal slightly over-size so it will hang over the edges of the piece I am applying it to. Next I apply some Microset to the area (Microset being a wetting agent to aid in decal adhesion), then place the decal onto the surface. I then pat the decal with some absorbent paper to help draw the moisture out from underneath (important when we are looking at such a large area being covered in decal). After about 5 or 10 minutes, I then coat the decal in Microsol (Microsol being a decal softener, it makes the decal conform very closely to the surface - very handy around curved wing tips etc). The decal will go very wrinkly when you apply the Microsol - don't panic and don't try and touch the decal - after an hour or two the wrinkling will dissapear and smooth out!
Once the decals are completely dry (usually overnight), I trim off the excess using a very sharp blade, always working perpendicular to the surface (that way the entire surface is covered in decal). I give the edges a quick dab of Microsol to reseal them. When using this technique on wings, I strongly suggest doing only one side of the wing at a time and letting all the decal dry before decalling the other side of the wing. This means that you can avoid unsightly "edges" where the bare plastic is showing along the trailing edges of the wings.
I use the same technique for the rib tapes - the Microsol allowed the tapes to conform right around the leading edges of the wings of my Albatros with some gentle persuasion and patience (although I did have to paint the rib tapes running along the scalloped training edges).
Once all this is done, seal the whole thing with a clear coat of your choice, and voila! I also used some post shading to "scale down" the contrast of the colours using an over spray of Tamyia "smoke" around the rib locations - I think this gives the lozenge a much more scale appearance - up to you if you want to try this of course! Anyway here's my results of using such a technique (this technique may not work for you, experiment a bit!):
In the next pic, notice how the Microsol allows the rib tape decal to conform all the way along the leading edge of the wings and even all the way around the wing tips (ie a complete 180 degree turn) - this leading edge rib tape is all one decal! Such is the magic of Microsol.
With Roden brand lozenge, I beleive that these decals are a little more difficult to work with in that they don't adhere as easily and require gentle handling due to being brittle when dry, but not having used their lozenge before I'm not really quallified to answer! I hope this is what you are after, if not, sorry for the long story!!
