i have a rough idea of the colours that would be used to do nmm parts, but i would like to know from the experts (u guys) what sort of colours are best to make a standard metal colour e.g. on a sword
Do a search on the forums for NMM colors and you should get plenty of results, and or any future questions can be answered similarly 95% of the time...
