Kelsey,

I've had the blue foam - it's 2lb density - for several years when I bought a 4" thick 4 X 8 sheet. This mold was cut out of my largest remaining piece so I'm going to have to buy another sheet soon. (I also use it for making plugs for fiberglass molds.) Most insulation foam company's have it and home supply companies like Lowe's have it - but sometimes only in thinner thicknesses. They do in my area anyway.

The silicone is repacked for Fiberlay and so has their part number. Last time I looked the Silpak web site was under reconstruction unfortunately.

Here's the general spec for the stuff ... maybe you can use them to look for other sources:

Cured Hardness: Shore A 28
Tensile Strength: 520 psi
Elongation at break: 310%
Pot Life: 1 hr
De-mold: 24hrs

For canopy copying there is an easier way if the original isn't so dear. I'll post some suggestions for that shortly.
