Signs on the barrels => decals? hand painted ? thin paper ?
decals printed on testors clear decal paper.
Mixed feelings on that : bought a pack of 3 clear and 3 white sheets.
first white sheet appeared bad (whole streaks that didn't take the ink) printing went well on another sheet, but then came the fixating and the setting. rather cumbersome and I'll probably have them printed for me in the future (got a friend who's in the trade, but have yet to ask prices)
The sign too was printed as a decal, but ink run out while applying microset and I ended up using my paper test print for it.
