I want to build up a couple of custom Fiero's. I have a few ideas I want to tryout on a spare Fiero body before I settle on the final renditions. Is there any type of material I can use to add dimension to a body part that can be easily sanded and formed, or even entirely removed if I want to go in a different direction? Does anyone know of any material that could be used? I was thinking expanding foam but I am not aware of its ability to be layered, shaped by knife or sandpaper, or its ability to stick to the surface of the car. Has anyone used expanding foam for this purpose? Also once I decide on a shape I would like to drape fiberglass over it so I am looking for something light.
Any ideas and insight is appreciated.
EDIT:As I am researching this, it seems that the dust from expanding foam can be toxic to your lungs. It can also be transmittted to others from your clothing. Sanding may not be such a good idea unless there is some non-toxic foam. What I am reading came from a few years ago.
