I've visited a jet-ski factory and I saw that they spray a gelcoat(polyester) on tool surface before laminating the first layer.
Does anyone know why they need to gelcoat at first ? I thought gelcoat only use for mold making purpose.
and how is a different between this gelcoat and gelcoat which is used to make a mold ?
Please kindly to help.
