Foam filler
Have any of you filled up a resin kit with Great Stuff foam in order to give a piece more internal strength? If not, Great Stuff, what have you used? I have a hollow piece that is quite flimsy, and I'm considiring using Great Stuff. Am I mad? Wait... don't answer that.
On the sixth day, God created man... primarily out of Aves Apoxie Sculpt and other greeblies found around his hobby room.
I believe (from memory of a similar discussion here, and reading the can not long ago while working on my house) you have to be careful of:
1) Over Expansion. The foam continues to expand for a while after the initial application. You wouldn't want to 'blow out' the sides of your model.
2) Heat. The foam generates heat as it cures. You don't want to melt or warp your model.
That being said, this is just theoretical, has anyone here actually used it?

Typically I use Epoxy putty rolled into a sheet, and inserted into said part. Then with tools make sure it adheres to the piece. Same with very thin vacuformed pieces. Back them with epoxy.

When I was building the two Minbari Cruiser vac kits I built, I filled them with the foam from Home Depot (I guess it was Great Stuff, red can, yellow lettering).
ANYWAY, yes, it will over expand if too much is put in, but there's a way to stop this problem. The foam sets by absorbing water from air. To stop the foam in it's tracks, do the following; spritz in some foam into the model in one stream, then spritz it with a spraybottle full of water, repeat until full. Works like a charm!

I've filled nosecones and such with Great Stuff...the only problem I've had is sometimes it doesn't cure if it can't get air...
I've started using a two-part foaming epoxy. Last time I got some, I purchased it from www.publicmissiles.com , but I've seen it elsewhere too.
