Silicone, Geocel? What’s the best sealant to use?

Hello, This is the best stuff but you need to use dish soap (dawn) on your finger to "work" this stuff Geocel 28100v RV sealant Don't use caulk Thanks, Joe

I replaced all of our clearance lights last year and used white exterior 30 year silicone. I'm pretty sure Monaco installed the original clearance lights using the same stuff as I had to scrape it off.
One caution, use something to retain the wires before you cut them as they will go down inside the cap and are tough to fish out. I used a pair of hemostats to hold the wires.

Good idea. Thx

I just replaced the front clearance lights on our 14 Sunstar. I used non-hardening 1/8" butyl "Tacky Tape".

I don't like silicone as it's hard to get off, and essentially glues down whatever you are mounting. As things shift over time from temperature changes, vibration, and such, silicone can shear and leak.

Also, I used stainless steel screws. Some of the zinc plated OEM screws had already rusted.

Make sure that whatever sealant you use, you seal around the screw threads between the back of the lights and the skin of the coach to keep water from weeping down the screw threads.

I used non-leveling dicor because I hate silicone sealant. I have since discovered Geocel Proflex sealant and would use it next time.

I have some 3/4” butyl tape I could cut and I now have the Geocel proflex. Gonna use one of the tomorrow. I do plan on getting the front painted later so maybe I’ll use butyl for now?

That's what I have always done too. I think the butyl tape is a huge improvement over the old caulk tape. It seems easier to manage that the more liquid sealants.
