I've finally reached the point where parts were ready for primer. Sprayed all with Tamiya light primer and metal primer for PE parts. Lots of primer was used. As with other OOB builds of plastic kits, that step signifies beginning of the finish straight for me. From that point it's straightforward, pretty much just painting of different colors, decals and assembly. Looks like this one might be quick as well, similarly to Lotus 79.
Quick snapshot. Sorry, my paint booth is a bit messy.
