2-pack acrylic is perhaps only 30% solids. I don't know about the clearcoat. They've probably used perhaps 1.5 litres for everything (2-pack has far better coverage than cellulose or rattlecan paint).
Paint is less dense than water, so perhaps the 'wet' weight of the paint is about 800g. I don't know how dense the solids are, but I'd be surprised if you saved more than 50g in total.
