I've got to drill the barrels? 'Stripe' was done by masking, hair laquer, spraying, scrubbing. Disasterously so! Mask bled and although I'd varnished the original grey, air-brushed surface it didn't stand up to scrubbing so I affected repairs with a hand-painted, new grey surface (got to love the covering power of Vallejo!). The blue was okay but I added another layer by with a slightly lighter blue mix dabbed on with a brush.
