Heh?
How are you getting through it, empty a bottle into a airtight container, drop parts in and seal it up for an hour, just keep re-using it until it completely evaporates. A bottle or jug should last months if not years
As long as you only put the metalic on "thin" and in 1 coat the black primer will dull it slightly, but nuln oil is a sure fire way to tone it down. The good thing with nuln is you can add multiple passes until you get the look you are after.
Well it turned green, I couldn't see what was in the tub lol. It would still have worked I'm just weird
Noted on the other bit, I really need to finish some models to a standard I am content with because I'll never be 'happy'. The white on the Iron Hands is stressing me out already.
