Sealant for hole

[MikeInOregon]

I drilled a hole in the pass-through storage floor to run a wire to the outside of my trailer. In other places on the trailer where wiring or plumbing runs from the interior to the exterior, there is a clear sealant to seal the hole. What is the clear sealant that I should use to seal the hole?

Use urethane if you really want the very best. Yes it comes in clear.

If the hole is decent size use spray foam to seal it, otherwise clear silicone

Clear silicone caulk.

Sounds like it is just ordinary silicone sealant.
