Compatibilty of paints and oil washes

Hi All,

I just posted this under techniques but it probably fits with the painting forum better.

I'm trying some new things with my Stug III and I'm hoping someone can help clarify some aspects of my techniques.

With this kit, I decided to preshade the whole thing with Tamiya Flat black lacquer from a spray can for convenience. I then will paint the basecoat in several thin layers by airbrushing Tamiya dark yellow acrylic. I'm trying to get the appearance of nice shadows in all of the recessed areas. Next, I'll apply any camo, again with acrylic and then a coat of acrylic matt finish. Here's where I am not sure what to do. I have previously used watercolours for washes with other kits but this time I would like to try using oil paint thinned with mineral spirits. Do I need to worry about the mineral spirits having any affect upon the underlying enamel preshade coat of black? Will the spirits even be able to penetrate the acrylic layers and get at the enamel?

Any ideas from your own experience would be terrific.

Many thanks.

Jim
