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.

It would be a lot like this. Taken from a post by Rowdyrenault in a current topic on the Ultima forum. It's not for an Ultima but the format and layout are similar.

Thanks RG. I'll give it a go.
