Hello all
Is it as simple as saying the weight of the can denotes its fullness, or is there a curve of weight in a spray paint can as some of the butane/acetone is vaporised/depressurised.
i.e. giving the effect of weight of can going up before it starts going down.
if can starts full at 420g might it first rise to say 430g as solvents inside are depressurised and then start falling until just the can weight remains at say 200g.
