Thanks Rob, It looks like my customer wouldn't let me to change the material. However, this potting material still sticks to the non sticking fixture that I have. Can anyone give me a non sticking material that I can make these fixtures out of?

I don't think could suggest anything different than what Rob has suggested. It's really nice to have such information. Thanks, Rob for sharing it.
