Those two people are (being polite here)mistaken, and they need to take a look at how Newmar and other reputable manufacturers seal the front and rear caps of their motorhomes.

I think your insurance company was not being forthright with you.

Yep his insurance company took him to the cleaners so to speak and Eternabond is a common way to seal the seams on slideouts on trailers that use Dicor elsewhere. It's not commonly used at the factory IMO because of cost and time and not recommended by dealers/service centers because it is harder to remove when doing repairs and cuts into their cash cow of the frequent inspections and maintenance needed to maintain trailers that use DICOR. Finally, it is a standard in sealing EDPM rubber roofs in the regular roofing world and TT that use EDPM for roofing materials are not really an exception.

With silicone in the mix it is hard to say but normally the recommendation from Dicor is to clean the old material and the just apply new over old. Old rag with just damp mineral spirits will clean the old Dicor easily. Let the mineral spirits evaporate before applying new.

I did that on my last trailer. However when I made an insurance claim they devalued the trailer because it was done. It took a long time to deal with that one issue I think I will stick to dicor from now on.

But thanks to all for the help!

IMHO you should remove all the old sealer every time and clean the surface withn a good alkahol based cleaner befor you reseal. A lot of times the problem is water getting under the edge of the sealant and leaking in.

I think before you cover the old with the new you should at least clean the dirt off the old for better adhesive

Now for the next question....Do you fill the little holes in the fridge vent cover with dicor or do they stay open. They had silicone in them when I took it off.

With silicone in the mix I think I would remove everything an start over fresh. Nothing sticks to silicone including silicone.
