Well, did my first ever full length, trim seal job, using the Dicor No-Sag. I've done the self leveling...that's pretty easy, but running a bead of sealant 10 feet in the air...or more since the rear of my camper hangs over my sloping yard. It would have been too hard to reach the seam from the roof side b/c I have a vent fan and other structures back there that hinder me from getting close to the edge, so I did it via ladder. Geeze, I pulled the tape after I was done and that stuff did the hair-like, spider web 'flyways.'

I used painters tape to help keep the lines from being too bad. Overall, it isn't pretty, but it's done. I'm going to ascend right now to check for any misses. Once I let it cure for a while, I'll be placing Eternabond along that rear seam.

There’s all kinds of bad advice out on the web. And you never know who’s getting paid for promoting particular products (like silicone caulk). I want to see the YouTube video where they try to get the silicone off years later. If you’ve ever tried, it’s h*ll to do, believe me. And new caulk won’t adhere well to old silicone. I’m with Grumpy on this — personally I like Geocel Proflex RV. Great stuff.

I think you're using the word 'silicon' synonymously with 'sealant.' Silicon is a TYPE of sealant that shouldn't be used on the exterior of RVs. There are MANY SEALANTS that are good to use, like Dicor products; self-leveling or no-sag formulas, Pro-Flex RV, which has version that can LOOK like silicone; clear, but is definitely NOT silicon. Etc. Etc.

Those pics are so far away any caulking job would look good Is that a white caulking, if it was clear I wouldn't see it
I still maintain a good RV approved silicon was the way to go for your trim job...it's like what they caulk with around the lights, a clear silicon.

Hahaha. You're right. After I came down from the ladder I thought "It's too far away to know how it actually looks."

Clear SEALANT comes in many forms, by many different manufacturers. The clear stuff I use is NOT silicone. Honestly don't ask me the technical name of it. I just know it to be, GeoCel ProFlex RV BRANDED 'sealant.' It is clear, but it is NOT a silicon product.

To each his own, but what you are talking about is silicone. Silicon is a chemical element used in semiconductors— a bit pricey for caulking a trailer.

I would not use it on the roof or anywhere near the roof material. Silicone has always tended to discolor when I used to use it to seal side seals. There is a brand that I use on outside seals called Lexel. Available in white and clear. It's the best.

Norty, I was looking at that stuff and was going to try it out the next time I might need a sealant for an outside wall fixture. End of last season I used the PRoFlexRv Geocel. Well, I sealed it alright. I made a bit of a mess too...but that's not the important part. : )

Using the proper silicon is key and not expensive or dangerous as LD suggest @26
What I like about silicon is that it will last a long time and you can do a nice neat bead by letting it sit for a minute then with a soapy finger you push the caulk in the joint/crack and smooth it out nicely with no edges. I do like the spray bottle idea as seen in that video...I've seen tape put on each side of the joint as well. Most people put too much on then try to fix it and make a mess as Judy discovered The key is a small smooth bead with no bumpy edges that can actually make a place for water to sit Nothing bugs me more than a smeared mess of caulking way wider than it needs to be

You totally missed my point. Silicon (no “e”) is an element used in computer chips. Silicone is the gooey caulk you love. As I said, use whatever you want, but it won’t be silicon.

Maybe LD, but we were talking about silicon caulking not silicon valley

Sigh. There’s no such thing as silicon caulking.

 

[Glamper64]

Yes but there's a Silicon Valley isn't there.

 

[Grumpy]

Yes but there's a Silicon Valley isn't there.

And here's why.....

AI Overview

Silicon is a naturally occurring chemical element used in electronics, while silicone is a synthetic polymer.

Are we posting to a trillion posts on Silicone to see who wins?

 

[Glamper64]

Looks like we are Jayhawk and all because someone missed an e
It reminds me of that old show "Trailer Park Boy's" where nobody could spell even though they all knew what was meant
I guess LD is the winer

Site Team note:
Lets get this thread back on track or it will have to be put out to pasture. How about we agree that the word is spelled silicone and just move on?

My experience when using this on a job for installing and sealing the surround of new tail lights on another TT dealt me with a big surprise. And I have run beads of caulking for way too many years with fairly decent success.

You better be careful on running too thick of a bead and then try to smooth it out. The surface skins quickly and when you try to smooth it, lumps showed up in the bead, where the underside did not cooperate in the same time frame.

In the traditional boating industry of days gone by and after Treenails aged themselves out, silicon bronze wood screws came on the scene. But when discussing refastening the planking by a lot of people many got a bit too comfortable in their typing and with the auto correct feature in computers the E ended up showing up when folks hit send. The discussion also spun off on just a display of innocence of not working with the types of screws full time. Word spelling changes all the time for me on many commonly used words when typing on my phone.
