I found product called, "RV goop". Stopped my worst leak in the roof. Is paintable, so is not silicon. Tube does not indicate that it is a polyurethane , but I suspect that it is.

One of the bigger suppliers of RTV is MGChemicals.
Here is a link:

You threw me a curve with that one, John.
Even though being involved with the chemical manufacturing industry for years I had never heard of MG Chemical. A bit of Internet research shows that they are primarily a wholesaler/ distributor to the electronics industry.
However, I find that they wholesale and repackage RTV that is manufactured by GE and Dow Corning and perhaps others.
But I see that you did say they were a supplier, not a manufacturer.
The big three in manufacturing silicone RTV are GE, Dow Corning and Rhodia (a French company).

Emery, I pulled this off of PL's directions.
"Do not use in joints deeper than ½' (13 mm) without the use of a backer rod. The depth of the sealant should be half the width of the joint. The maximum depth is ½' (31 mm) and the minimum is ¼' (6 mm).
some of the seams on my front cap are 1/8" x 1/16" deep. Way smaller than recommended. ???

Pete,
We use butyl rubber tape for the window sealant. It comes in 25 foot rolls and it takes 3 rolls for all six windows. If you can't find it, we can send three rolls to you by Prority Mail. The butyl rubber tape never sets up and will give with the coach flexing as it goes down the road. We can send the installation instructions for the windows with the tape if you want.

Thanks Gene, I have a few rolls on hand. Ive already used a couple mounting A/C's and replacing a couple of windows. (No leaks so far) Previously I sealed 95% of the window leaks on my old style windows with the "Jim B. rtv/ blue tape treatment" around window frames.
I just assumed I'd do it again. I guess I don't need to?
Comments please!
(using 76-78 windows)

PS: Thanks all for the straight scoop on usage of rtv and polyurethane sealants.
These annual hurricanes and tropical storms are truly the best way to eliminate those leaks one by one.

Gene what are the dimensions of the butyl tape and where is it applied?
I have a set of windows from a 78 that I will be rebuilding and installing in my 75.

Les,
The butyl Rubber tape is 1/2 inch wide and 3/16th inch thick. The roll is 25 ft. long. You start at the middle of the lower part of the window and apply the tape around the window to where you started. The tape should over lap the edge of the frame slightly. When you put on the window in place you should have spacers at the bottom of the frame about 1/4 inch thick to hold the window. Someone needs to be on the outside to fit the window and hold it in place until someone can anchor the window in place. Tighten the window and you will see the tape extrude around the frame. Wait about a half hour and retighten the window and you will get 2 or three revolutions on the screws. Do it again until the window is tight against the coach. Then remove the excess tape around the window and you will never have a leaky window. It takes 3 rolls of tape to do the 6 window coach.

This stuff sounds much like the adhesive tape I've seen used to bond windshields into some older cars. Newer cars with airbags require adhesive with higher bond strength so a curing urethane is now used.
How is the butyl rubber for cleanup when removing the excess around the exterior? I imagine you need some solvent like varsol to remove the remnants?

You really don't need a solvent to clean up butyl rubber sealant but you can use it if there are some smears.
Once you tighten down windows or skylights you just trim off the excess that squeezes out and peel it off
The butyl tape is usually black but it can also be found in white.
It comes in 1/16", 1/8", 3/16" and 1/4" thick. It might even be found thicker. It usually comes 3/8", 1/2" and 3/4" wide.
When I owned a window/ door distributorship I had all these sizes in stock.
You can find it at about any store that sells glass or skylights. I have also seen it at camping or rv stores.
