Thanks...I have seen that product and it is interesting. The part that pushed me away from it and toward pourable silicone were comments I found online about exothermic compounds (like 2 part epoxy) could be too warm for it and if so might cause the mold to deform as the epoxy went through its curing process.
Besides, there are not many options for replacing the radio delete plate, so I was hoping for a way to make a mold that might be useful many times. As you know the fiberglass or fiberglass/epoxy process takes a while to do correctly, but I've been told some of the delete plate reproductions out there aren't very good.
