Brilliant Fluids
Patience has paid off! In stead of stripping the front fender from the terrible italeri decals, I left it as is, and started searching the web for solutions. I read some brilliant tips on the forms at www.modelbrouwes.nl, and went to the local model shop and bought some Microscale SET and SOL decal solutions.
Actually, de bottle labled "SOL" proved to be the most useful. After you applied the decal, and it is all dry (like my carbon fender struts), you gently apply the SOL fluid to the decal with a soft brush. As you may have guessed, SOL stands for "solution" and that's what it does, it dissolves the decal slightly. The decal becomes so soft you can push and stretch it with the soft brush. Don't overdo it, if the decal won't go any further just let it dry, and try again tommorow. Sometimes it takes 2 to 3 tries.
The funny thing is that when the SOL fluid is applied, your decal may start to wrinkle. Ignore this. Just let it dry for a few hours (don't touch it!) and it will straighten out. Really great stuf!
The SET fluid smells like vinigar, and you are supposed to apply it to the model before you put the decal on. I have tried it, but I haven't seen the benefits of it yet. Maybe the SET fluid de-greases the surface a bit, but since I keep the surfaces clean anyway, it won't do much for me I guess. I have a lot more twisty and lumpy carbon parts to do, so maybe I'll get back at this...
