I have a 2011 Sunseeker 2300. I am wondering if anyone has applied Eternabond to the molding where the front face of the cab-over compartment meets the sides of the compartment? (I am referring to the older-style construction, not the new fiberglass caps.) I realize that the Eternabond should probably not be wrapped around the edge of the molding, but is there any reason it should not be applied to the forward-facing surface to protect against water infiltration? (This application would result in part of the Eternabond being “upside down.” See the following paragraph.)
As a related question, has anyone applied Eternabond to the molding that covers the bottom seam of the cab-over compartment? (I am referring to the molding that runs across the bottom of the compartment directly above the cab.) In this case, the Eternabond would be attached to the underside of a horizontal surface. In other words, it would be “hanging” on the surface rather that “resting” on it. I wonder if anyone has had any success in using it in this inverted orientation. I know it is sticky as all get out, but am not sure if it is designed for this application.
Input from those in the know would be appreciated.

If it WILL stick there, and CAN stick there., and you WANT to stick it there..then stick it THERE!
One it is placed on a clean prepped surface and rollered till the microbeads burst..it's there to stay! Even underwater or a pouring rain storm. Amazing stuff!

Thanks for the info. I have applied Eternabond to all the roof seams so I am familiar with how tenacious the stuff is. I would like to apply it to the areas specified in my post, but wasn’t sure if it would adhere permanently in the inverted position. Looks like I have another Eternabond project to get involved in this coming spring.
Forest River offers a one-piece cap as an option to cover the face of the overhead sleeping compartment. I submitted a change order during construction to include the cap, but the process was too far along to make the substitution. I see no evidence of any leaks at this time. I just want to do whatever I can to ensure I never see that kind of evidence.

Yes, it will stick. Eternabond is a great product.

Yes it will stay in place inverted or any other way you want to place it.

I found that I needed to apply a little lap caulk to the edge of the etrenabond to make sure it did not peel up a little. once I did that everything was great chuck

Yes, I did exactly the same to my class c. I had 4" eternabond. Cut it into 2" strips and did the seamrunning down the front and side of the cab over. Rolled it with hard roller just as instructed. Then, did underneath. Worked just fine.Its not as neat as the factory job, but much more water tight. Mine was 9 years old when I did it.

Jwgirardi,
Thanks for the info. It is good to know that someone has successfully used Eternabond in exactly the same application in which I am intending to use it. I have ordered a roll of 2’’ Eternabond and await warmer temps before making the application.
