I’m a fibreglassing virgin so please bear with me. Don’t hold back if I am talking rubbish.
I want to make a radiator fan shroud so the form would be like a big biscuit tin lid.
I could form the shape in foam over the back of the radiator and then make a mould. But making a mould seems a lot of work for a one-off and how to allow for the thickness of the final laminate along the turned-down edges. The turned-down edge issue could be avoided by either not having one making mounting and sealing a bit more difficult or by bonding on a pre-formed angle in situ.
Another way could be to build directly onto the radiator and foam. But how to get a decent surface finish – especially if I go for a clear top coat to show the cloth weave below. Maybe that would be too ambitious but I do need the surface to be smooth.
Thanks in advance for any advice and comments.

Reckon your best bet on this job would be to take a simple splash mould off the back of the component, doesn't have to be anything special in terms of thickness I think you would need about 4mm total thickness, this way you can also pick up the locations for any mounting holes etc.
In terms of component thickness just take a pair of calipers to the component and measure the thickness then you can decide on the amount of layers of carbon you need to use. With carbon only 3 to 4 layers of 200k should suffice.
Hope this helps matey
