First of all I would like to thank you for your comments. It helps me a lot with the build, and keeps me working on it.
@gblair Yes, George, kabuki paper is much more expensive, but I use it occasionally, only when needed. As of today I still have 4 and a half sheets out of 5 from AMMO (AMIG8043). Mostly it was canopies and masks for curvy surfaces.
What I like most about oils is that you can remove it and start once again in a case of some issues. And blending of course.
I've finished with a "wash" on the upper surfaces, and next I would like to fix it with a satin coat, so all other oil layers would not interfere with each other. Or I'll move to the bottom surfaces before the satin. Anyway, I will leave it at least for tomorrow to check everything once again before moving to a next step whatever it would be. I'm not sure about the final result, and I'm treating this as an experiment. My current assumption is that it's too much of a contrast, but will see. Intermediate steps may look suspicious.
