Oil colour

Hi everyone,
I´ve got a question for you.
Has anybody ever tried to use regular oil paints with
the real-skin technic??
With the thin layers of paint it seems like it would work
since the paint dryes quite fast when thinned out so much.
I´ve been trying it out on old playdolls, and it seems to work
but I don´t know if there will be problems later on.
The only thing I haven´t overcome yet is the wee bit of "chalkiness"
in the fleshlayers.
Anybody tried this???
I´ve been rebornig a couple of years ago with the technics used
then, but now I would like to try it again in the modern technic.
I´m a bit sceptical about the heating process though.
