Thanks, this is my method: On explanation I use my earlier figure (Steins,Gate - Makise Kurisu)
1. I use modelling material (photo 1), who I glued on the model (m. material is wet still ) with gel superglue (Loctite power gel) (photo 2)
2. I'm waiting when the modelling material is dry
3. I use to mask acrylatte putty (photo 3)
4. then you must a lot of grinding ... (photo 4)
5. I use Spray Paint (photo 5), or revell color on small parts
6. ... and here is the result (photo 6)
