Tubs directly on flexwatt?

[Vypyrz]

Well I'm buying 2 feet of flexwatt, dunno what I'm goin to use to tape it on. I have a price of glass I could tape it on, gota see what I have at home. What else can I use?

I am in the process of setting mine up similarly. I am using melamine shelves that I had cut to size at Lowes. You can also use Polystyrene insulation. I actually put a notch in mine for the probe to set in under the heat pad so the tub wouldn't wobble on it. I'm not done with the project yet but I can get some pics up later this afternoon of at least that part of it...
