Aluminum foil or blue tape??? for custom seat

[OhioEric]

so then, how much do you use on an average seat pan? a quart?
how many layers of cloth, on average?

A pint will do for your job. You will want a few layers of cloth. Once you think you have what you want the foam can be dissolved out leaving just the glass part. Then if it is not stiff enough you can add more material

Another option is to trim out most of the foam and leave a thin layer and apply a ply of glass to the inside and you will have a sandwich construction.

so 3 layers or 4?

mat or that woven cloth?

does it matter?

Your choice on fabric, I just work with cloth. There are so many variations in the fabrics that will vary there formability and strength characteristics one can not just say 3 or 4. Each part and each layup have there our caricature.

The more curves the stronger the part and thinner it can be. Flat areas should be thicker.
I have made tail sections with one ply of 8 OZ cloth that were fine, but a bit fragile. There was no taillight hanging off it though.
