Yeah, Don. I tried the CA and Baking Soda mix but it comes out like crystal and is really tough to sand down. But, it is lightweight. For a quick fix, I'd go with the sawdust and CA... probably just as light, or for an overnight thingie, sawdust and epoxy, which may be a tad bit heavier. For Glow, well, that won't matter much. Electrics, well, used sparingly it should be fine.
