Thank you for that. You've basically gone against your own suggestion is to use the BLACK for BASE "because" it's the main region for METALLIC FLECK! You are right though, You can use any region for anything because it does work. But at the end off the day if you want a livery with both Metallic fleck and chrome but follow the idea that you can use BLACK for Chrome....... Best off luck with that. I've given my suggestion and guides as to the how I would do it being a very experienced painter who has a clear understanding off the work flow for this system. It's up to the readers to choose experience over guess work.
