What sealant do you use to seal along the top of windows, doors and other openings? Dicor non leveling or what?

I use clear RTV from WALLY WORLD. It stinks like crazy but has yet to fail me.

x2 It works great and does last.

The Dicor is primarily for EPDM roofing. I like Geocel Proflex RV for all other uses. It comes in clear and about 10 different colors.

Newmar and others say not to use silicone except to cover the real sealant. Also, silicone is hard to remove and nothing sticks to it.
Newmar uses Sikiflex on some of their units now or at least that's what is on the Essex we've been looking at.

Sikiflex is used alot in the construction industries. I believe it is latex based. And quite right on the silicone. Nothing sticks to cured silicone not even the silicone itself!

Silicone also has the advantage of being VERY flexable which is a big plus in RV use. Yes nothing sticks to it you have to be selective on where you put it. Me I don't care I want sealed and never have to worry about leaks.

Silicone isn't terrible to use where the OP stated, e.g. over windows and doors. And it peels away from those places fairly easily if it has to be replaced. However, there are now clear, non-silicone sealers that retain flexibility quite well. I would choose one of those vs silicone.

I would never consider silicone on roof seams or body joints, though.

Gary what would you use for cab to body joint on a C class?

A friend of mine who did a LOT of home inspections says not to use silicone, but use a buytl product instead. He says silicone doesn't seal well. Did you ever pull old silicone caulking off of a bathtub edge? It comes off easy because it doesn't stick. He said there is a lot of mold problems in walls that supposed were sealed with silicone.
