Body sealer

Two questions here really.
#1 recently added fans to fridge exhaust at roof and had to take the cover off.
The four screws in the cover went into molded recesses in the cover, and were sealed in with a white elastic sealer.
Anyone know what that was? I need to replace it.
#2 some of the things attached to the outside of our Coachman have a white sealer around them but the windows and access doors do not.
Anybody know what that sealer is ?
Here's a couple examples:





As always, thanks!

Dicor.

Some Dicor tubes are for horizontal and some are for non-sag areas.

For walls, do ensure one buys the non-SAG version.

I recently recaulked a couple of windows. The local RV dealer uses and recommends Nu-Flex 313 fast set silicone for things on the side. I used RV putty between the window and the coach sidewall. Then I sealed around the perimeter with the Nu-Flex. I would not recommend Dicor on the sides of the coach, at least not the self-leveling kind. I don't know if there is a different Dicor product that people use on the sides. Anyway, I found the Nu-Flex easy to work with, and the result looks very substantial and professional. YMMV

Let us know in a couple of years how that silicone is working for you.

Yes, there are different formulations of Dicor, one made especially for wall joints.

FWIW, silicone sealants are good for mating surfaces in compression. They will break down fast if left to weather on an exterior surface. Nothing will adhere to a cured silicone sealant, not even more uncured sealant. A better choice is the aforementioned Dicor or Geocel Proflex sealant.

On our new Cougar they used tons of ..looks like Dicor around all the vents on the roof but used a clear sealant on all the fittings, doors & wents on the sides.

Most likely Dicor
