Ive used that and it was fine and now use DAP kitchen & bath brand (same thing diff brand) for all my thermometer probes and to close of the rest of the holes i drilled in the PVC for wires. I Love it. Hardly any smell. Not like that silicone i get from AP when I get new enclosures. Thats stuff stinks terrible and stays gummy imo. Every time i clean the enclosure the wetness makes it sticky and catches on the paper towel.
