I obtained a 7 plank without opening end door cheaper than buying an unpainted version.
A quick rub down with a glass fibre brush removed most of the printing.
It was then undercoated with grey primer and , once dry, had the top coat of green applied.
Again , once dry the ironwork was masked up and touched in with matt black.
They really are simplicity itself to do- even I can do it!
The result is a crisply lettered wagon which hasn't broken the bank.
I have several unmade kits in stock plus a few RTR wagons which can be utilised.
