Molotow coverage input needed

[CGClone]

I’ve used the pens but not through the airbrush just yet.
For those of you that have shot it through the airbrush, I know you have to lay it on somewhat thick-ish? But my main question is-

Say I have two iron man helmets I want to paint, about how much Molotow liquid chrome would I need to cover the full helmet, how far does one refill go?

I painted a 1/4 scale T-800 and a 1/1 Endoskull from a refill. The stuff goes pretty far. I only painted those 2 things so I am no expert inits use. It will be chrome on any surface so smoothness is key. It’s also very thin so while you want a wet coat,take care not to go so thick as it drips or puddles.
