The interior of the case might end up being pretty awkward, which is why spray seemed like a neat idea. The even coating business might be a bit hard from an aerosol can though. I would likely go overboard and do a few applications to get a nice coat, but I'll have no way of verifying the thickness. > I would go with copper foil tape and copper mesh if the entire box > needs to be shielded.

I thought about trying to do that, but I don't think it'd be that feasible. There will be enough living off the PCB that I think the entire box really needs to be covered.
