That way you can wet lay the resin onto the fabric and press the two together to ensure the fabric conforms. You would probably want an excess of resin laid onto each metal sheet to try and ensure air does not get trapped on the surface anywhere. if clamped tightly then the sheets will help squeeze out any excess resin. A gelcoat would be a nightmare to apply evenly so best just use resin. Also I would use a chemical release agent rather than mould release wax as it would save you time over the waxing manual process.Vacuum bagging I would rule out as you have to get the bagging film neatly into every single recess .
