Romanian 109E Update:
Decals are LF (from Czech Rep.), never used them before, come on one backing sheet so need lots of careful cutting-out. Quite thick and don't respond well to solvent (Mr Softer). Biggest issue was the lack of 'depth' in the yellow - more like a primrose tone, so had to gently blend in a deeper yellow using W & N oils, neat from the tube.
Looks a lot better now.
