Changing Outside Entry Light

[2StrokeDiesel]

Looking to change out porch light with the new one that has a motion sensor built into it. Question - What do I use to seal the fixture to the coach so water doesn't run behind it. Thanks again guys!

I would use a high quality silicone sealant in an appropriate color. I have noticed that some black silicones are more of a dark gray, the RTV black silicones seem much closer to black.

We use sikaflex for boat and rv sealant , very tough and stays flexable, rv places sell it. It comes in black or white, but if you want gray you can mix the two to desired color. Much better than silicone. But for a porch light high quality silicone should work

Butyl tape maybe ??? and then caulk around the top and sides.
