I'm in the process of pulling and resealing all the windows in my 13' Bigfoot.
I use Dicor caulking. It's made for rubber roofs but works well on Eggs.
Anything is better than silicone.
It's taken me almost as much time to remove the silicone as it did removing and replacing the first window.

Interesting info here, even if its almost 2 years old. Back when I was uneducated and had a metal camper with some leaks, I had a mobile RV shop come out and they taped and rolled the roof with rubber coating. They then applied acrylic latex chaulking, in a thin, neat bead, around all the windows, vents etc. Removing all these protrutions and Butyl tapeing them would have been the correct method but I wouldnt have paid them to do that and didnt have time or experience to do it myself. Now that I have my beloved Casita, things will be done right on it. More time, money and Im keeping this one.

Question, I'm pulling the windows out of my 2001 Scamp. They are louvered and square with silver rivets on them. Lots of silicone to get off from previous owner. I got black rivets which look much better. I used butyl and it squeezed out nicely all the way around. It looks nice an clean now. Do I need to put a bead of flex seal around the edge or is the butyl good enough?

I never "Double Seal". But not to worry, the silicone bead will usually peel right off after about 1 season.... LOL

Your fine with just the Butyl.... I use the edge of a plastic scraper and get in nice and close....clean up the residue.....done.
Butyl is the best

Thank you for the great visuals! I have five burro windows to re-butyl and you have made it so much easier!

Flexible Seal

I’m unsure of the exact product “Flexible Seal.” I have located two possibilities:

https://epmar.com/knowledge/technica...0VOC_FSC75.pdf
and
https://epmar.com/knowledge/technica...Seal_FSC60.pdf

How close am I?
Is there another non-silicone caulk?

Depending where the leak is, sealing along the window gaskets will accomplish zip.

Removing windows (one at a time of course) is not really a big job and does not require a lot of expertise either. There are endless threads on resealing windows, I just read a few and benefited from the knowledge and expertise of others.

If there was a viable short cut, everyone would be doing it.


Its that old saying, there is never enough time to do it right, but always enough time to do it over.

Now if you don't have a molded FG trailer, there may be other options.

As has been pointed out, most silicone is poison for this kind of thing, since is loses its grip and provides a path for the moisture to penetrate.

I have removed several items and resealed them and the old silicone has provided graphic evidence of failure. Bad stuff.
Seems like overkill? Why use both tape and caulk? I don't want to work with caulk for several reasons. Thanks.

Which post are you referring to? Flex Seal is a brand name which may be mistakenly referred to as Flexiseal or Flexible Seal.

I recently used Geocel Pro Flex sealant. It is a non-silicone sealant "specifically designed for the recreational vehicle industry."

Please forgive my ignorance, I'm a newbie. Where are "webshots?" I looked under a few pull down menus but didn't find anything. Figured asking would be faster. I would like to see these pix.

webshots is just one of the many photo hosting sites out there on the internet. A place where you can create an album and then upload your photos to it and give people a link so they can see them.

Except that they probably won't follow the link, so they probably won't see them, or the link will be broken. I wish Social Knowledge would make posting pix on their forums as easy as Facebook ( eg. ).
