Foam?

[bshmerlie]

Any home improvement store...even Walmart carries it. I did the background of a medium exoterra with 2 cans.

Expanding polyurethane foam. Don't get the fire blocking kind. Great stuff have several types - the window and door stuff expands the least. There are also pond versions - Tetra has one that is black (nice) and you can get this at some hardware shops.

Great Stuff is sticky! gloves are a must! also, for me at least, whenever I have some GS left over in a can, by the time i come back to it, there never enuf pressure to use the rest of the can, so its better to use it up quickly rather then letting it sit a week and then coming back to it, ive wasted at least 2 cans having them lose pressure. its frustrating!

Yeah, id have to wear gloves, I do tattoos so, fortunantly I have surplus of them lol

What is the best frame to use?
I have metal mesh I can bend & cut into pretty much any direction, will that work?

well if youre talking about a background, I never used any sort of frame, most people just spray the GS right onto the glass, and it bonds real well. Be careful using any sort of metal that could get too moist and rust. If you need landscaping tiers or whatever, under the foam, most people go the egg crate route, the same stuff u make the false bottom out of. you can make all sort of shapes and supports with that stuff.
