Sealant Blowing Out from Front Corner Trim

I'm 99.9% sure it ISN'T SILICONE.

Post up a pic. Most corners I've seen have Butyl Tape and a sealant. Never use Silicone on an RV.. bad stuff there.

There is no tape involved - that is one thing I'm sure of. This was some sort of flexible material that strongly resembled silicone. We were alerted when a string of the stuff start waving on the breeze as we were going down the road. When we arrived, I was able to pull out more strings and examine.

It had the appearance, when in place, of caulking. Not sure if it was applied after the trim (there is a visible cailk bead) or it was more of an adhesive squeeze out.

I will try and get some pics.

Here are some pics. One showing the caulk bead in place, one showing where a section blew out and one showing the trim piece in question. I;ve just been informed that a piece of trim along the lower curve has fallen off.

So now, before I call some one, I need to know if it is called something other than trim or molding? Anyone have luck ordering parts direct from Forest River?

Thanks for any help

Butyl tape isn't really "tape" in the traditional sense. It's more like rope caulk. They call it tape because it's applied like tape but it's thick and is meant to squeeze out when applied.

The sealant is something similar to Pro-Flex

What is bad about silicone ? When used correctly it works great and last for years.

Thank you very much. Turns out that Amazon says my better half ordered the stuff on her own.

Silicone doesn't clean off completely and is too weak to handle the stresses of flying down the interstate at 70mph.

It makes a mess on a camper. Never use it.. you'll be hating life if you do.

There are three different colors, white, clear, and black. Most popular is white.. I probably wouldn't put that on your camper. Clear or black would be fine.

LOL. Sounds like she's on top of it! :-)

Silicon is equally bad on wood. Messes up any chance of finish repair or finishing at all.

And silicone won't stick/seal to itself so if you ever use it and then need to go back at some point and apply more to fill a crack, you've just shot yourself in the foot.
