These 3 models took an hour and a half from spray undercoat to applying varnish.
I used a small fan to speed drying as it is pretty cool here currently, in summer I wouldn't bother.
I wanted something reproducible, natural and would not involve sub assemblies and any detailed work. Also could be used on tine bugs all the way up to the big ones.
