Very easy Rob
All cans were warmed before use.
Grey primer for the underframe then matt black - buffers were chemically blackened by dipping in Gunblue and rinsing.
Silos and all ladders etc were Halfords red oxide primer then red oxide primer! I used their lacquer varnish as prep for the transfers on the silos followed by dulcote from a can once done
I brushed humbol gloss varnish - the bottled variety - Glosscote - on the sole bar before the small transfers went on there - followed by coats of warmed, shaken canned dulcote
once the tranfers were settled.
Yellow bits were hand brushed white and then Vallejo acrylic yellow. the two big wheels on top were kept back, sprayed white and then a Halfords yellow I had in stock - but finished with the Vallejo yellow. then installed.
I made up a simple jig from balsa wood (easily cut to shape) to mount the top half while I painted it.
