The colours I was missing arrived so I could continue with this build.
Several parts was painted black, and I also repainted the engine and air filter.

Some parts like the seats and other interior parts is supposed to have a semi-gloss look. It turns out I had no clear satin colour, so instead I used Vallejo’s gloss for metal finishes and painted a thin layer, thus achieving a satin look.

I gave the engine a little more paint to get a glossier look.

I need to mask the mid console and paint that semi gloss later as well.
Once everything is dry, I’ll mask the interior roof and paint white primer before painting it pink.
That way I can check for imperfections as well.
