Window Sealant/Silcone

[AzRocket]

Wondering what to use. The stuff that is on my trailer already (around the windows, door, storage compartment, etc.) is (or was) white. It also never hardens completely. I want to get some more for sealing a few spots. What is it? Might have to zoom in on the pics to see what I'm talking about.

While Geocel is an RV recommended product, I won't likely use it again.
It gets really hard after a year or two. I will post some photos of my truck camper when I get home today.

Proflex is good for a year or two, then it will turn hard as a rock. It also seems to gro mildew where bugs got stuck to it.

Sikaflex is another product people recommend, but I have never tried it.

I agree here. This is what to use.

most have the butyl tape between the window/siding then covered with white silicone type at least at the top and sides; that's how they did mine, sure looks/feels like white RTV "silicone"

I advise against silicone. Butyl tape is available at most Lowes, Home Depot and Ace Hardware stores.

Ok. Well, is there any type of "silicone" I can use that stays pliable? If not, what does everyone use to fix things up. For example, I have been messing with my timer and switch for my fuel station. I need to seal it back up. What should I use?

A plastic scraper works wonders to clean the excess and make things look good again

What you are looking at is called butyl tape.
It is applied before the window is installed.
