Progress continues on the CIE bogie TPO kit. Got some weathering done this evening. Mix of weathering powder in solution (50% decalfix+50% water) and then airbrush for roof dirt, under frame, bogies, coach ends, etc. Next up gloss varnish in prep for transfers, then fit grab rails, letterbox cover, toilet pipework at one end, matt varnish to seal decals, glazing, pop on the chassis and finally couplings. Really enjoying this kit.
