Silicone concern and questions.

I have a 1992 Excella 25 footer. It has a trim piece about 2" wide that runs all the way around the trailer at the bottom. It's the trim piece with the blue plastic strip in it. Anyway, the PO put a bead of silicone along the top edge of this trim piece where it joins the body of the trailer. I've heard bad things about silicone. In this case the bead looks tight. Will it cause a problem with the aluminum, i.e., etching or some other problem? Should it be left alone or removed? Is it worth the nightmare to try to remove it? It runs all the way around the trailer!

Thanks,
Doug

Sooner or later you will have to remove the silicon.

Prior to that, the sun will break it down.

Then, if you wish to install the proper sealer, you will have to remove every chemical trace of the silicone, in order for the new sealer to bond correctly.

I would leave it alone if it looks ok. Yes, it can be a real nightmare to remove. Just don't put any more on the rig yourself...lol.

Don't know why you're trying to remove the trim, and both of us don't know WHAT kind of silicone was used.

If the PO used Silicone II, you'll have no reaction with the aluminum.

Not so with the plain old Silicone.

Good luck!

Thanks for the info. I'm not trying to remove the trim. I just was wondering if the silicone will react badly with the aluminum and cause me problems in the long run. If it's liable to damage the aluminum, I'll make time to remove it as soon as I can. If not, I'll leave it until it starts to deteriorate and remove it later. From one of the posts, it sounds like it depends on the type of silicone used. It sounds like it's hard to tell the difference once it's dry. What kind of problems does the plain old silicone cause?

I'm not sure of the problems it causes, but what a pain to remove the PO has it around every window and I have been working hard to get it off. I'm going to Parbond all the seems when I get all the old stuff off.

The plain old silicone has a damaging cosmetic reaction with the aluminum. If it's been there for some time, I would suspect the damage, if any, has been done. If you're not trying to remove anything, there's no sense in fretting over something you can't see.

That said, I'm sure many unknowing owners have used the original silicone over the years. ;-(

On our trailer, an old silicone repair of the TV antenna caused an area on the roof to deteriorate so badly that we had to put a reinforcing patch on it - the aluminum had gotten very thin as the silicone "ate" the aluminum. It was much worse that cosmetic damage. Newer silicones have been formulated differently and don't do that, according to what I've read here.
I don't trust silicone!
