RV roof to side gutter question?

[Red Fire]

Thanks Randy, at least I now know why the rivets are there.

How did the Dicor hold up?

Better than the silicone?

I was looking at getting the highest level silicone (flex, cracking, etc.) I could today and sealing it back up.

I have to pick up some Dicor anyways.

It's 100 today but rain will come unexpected this time of year.

There was also some caulking in there as it came out some white rubbery and some white powdery.

They had a problem by design, where in that area the Filon would banjo and make popping sound while driving under the right wind conditions.

That's an old guy fix as is all the caulking, your going to have to put some caulking there now to keep from future leaks.

What we would use is Dicor 502-LSW and start about 5ft back of the front cap and work forward, do this sparingly as this self leveling. So apply it and leave it alone, the tape is a good idea

Do you recommend Dicor over silicone to use around windows, side compartment edges around outside lights, etc?

If this is Filon could you buff/polish and seal the roof just like the sides of the RV?

Or would that be a bad idea?

OK, called Winnebago they said: You could polish the roof but don't need
to. They also said they never have had rubber roofs only fiberglass and aluminum.

He said to use a urethane sealant (dicor) to seal the roof to the gutter. Thanks Randy.

Also recommended the tape it first idea. Thanks Jomax

As for the sides : on hold and I know you can only edit for 20min. before you time out. So I'll answer in a minute. D nm it timed out during the edit but if you click the x the copy your writing you can paste it in a new reply.

Sides Urethane NON self leveling.

Dicor is for roofs only it is the sealant you find on the roof seams and around vents very thick and rubbery.

Will run if you try to use it vertically for more than a few inches

Did some research online and found this product.

ProFlex RV Flexible Sealant - colors: clear, white, almond.
around $9-$10 a tube. If you have a Camping World (they have it on line)or something similar I'm sure they have or could get it for you.

I went to the RV store and they are going to order it in for me. He said he had used it before and that it works great.

I will let you know, it don't get in until friday so it will probably be the weekend before I get to use it.

I'm going to use it on the roof to gutter and sides.

He said you could use the dicor on the gutter but to use only a small amount then smooth it out so it won't sag.

Just to add, Dicor also has a "Non-Sagging" caulk that does not run when use on vertical surfaces. The stuff really 'skins over' quickly.

I found this on another forum, they said this is what Winnebago was using.

The other info I found also said, what ever you use (silicone, urethane, etc.) DON'T mix clean off old and use one or the other.
