Late on this, but there is a material called Bond-Tech GS 112 rated for electronics and cables. It is also food-safe and stable (solid) to 85C +/- 5C. This stuff is NOT meant to be re-worked, nor would I think that any liquid-applied material would work well that way. It would have to dry out in a way that does not adhere to the substrate to be easily removable. Which seems contrary to the intent, unless very temporary.

Just a thought.
