I watched a Tested video where Adam was showing how to do paneling for a scifi model. Several times he mentioned using Weld On and said ILM guys had used it. I've also heard it's very toxic. I can't see anyone using it if it was THAT bad. So is it, or do they mean it's bad if you sat there huffing fumes all day, not just using it for minutes at a time? Also I've never had good luck with liquid glues, like the stuff Plastruct sells. My parts usually lift right off. So say you're gluing a flat piece of styrene, say 1"x1", how far does the liquid glue get sucked under it to bond? The times I've used it, it maybe flowed in 1/8".
