Door window sealant needed.

bighatnohorse pretty much covered it for me.

I have a 1988 fiberglass TC. The manufacture used silicone sealant all over it. for years it has typically failed to bond in some areas, and looks bad even where it does bond. I have no idea why they put it on the TC, there is not one place where it seals anything even where it bonds. I am still peeling it off.

I think the problem with RTV and other silicone sealants is "reverse-ability".
I usually do everything once, and breaking the rear door window hasn't happened yet.
So I assume that I may have to replace that window sometime in the future. Removing silicone is a very tedious job and no need for it when there may be other equally effective sealants.

RTV works and works well. But like others, I tend to shy away from the thought of removing it, ever.

I did put a plastic stopper at the bottom of my rear window like Notakwanon did to prevent the window from sliding down.

I have to ask (in this particular instance) why not? RTV and glass go well together and if I remember correctly, the glass on my Lance rear door sat in a recess anyway. Was just a matter of applying a bead of RTV and screwing down the plastic garnish. I would never use RTV anywhere else and never have.

Been a few years since I did it and I sold the camper to a friend and he uses it all the time and far as I know it's been zero trouble (door glass).

My new camper came with a clear door glass, heavily tinted.

I replaced the frosted one in my old Lance with a clear glass years ago and used clear RTV and when I sold it last year, it was still fine.

Whatever adhesive was used in the rear door glass in my camper gave way after 8 or 9 years, allowing the glass to slide down, leaving an open gap of an inch at the top. Got to admit that I did not see it instantly. With the frame off and the glass cleaned, I slid a strip of ethafoam into the hollow door underneath where the glass goes, so that even if the adhesive gave way the glass would not move. I used a silicone sealer to finish the job.

When we had new clear 'black' glass cut for our door replacment local shop gave me a length of the tape. A thin black mastic of some type, sealing glass to frame, applied like double sided tape. I dont know where you might buy it other than glass shop.

Frame to door used butyl.

I use butyl tape only. Do not use the clay type. Snug the screws down till the tape oozes out all around the window, trim with a plastic knife. After a few weeks, you will probably have to trim it again.

I put the tape on so it hangs outside the frame about a 1/8" to 1/4". Trim the excess.
