Where to buy Butyl Caulk?

Can someone reccomend where to buy Black Butyle Caulk? The kind you put into a caulk gun. I cannot find it locally, have found it online but not sure what type ( there are two) and the shipping is outragious. Planning to finally put in my windows next week and think I may need this for the job. It is not in hardware stores, or RV supply places. Am at a loss. Any help is appreciated.

What's wrong with butyl tape?

How do you use the caulk type when doing your windows?

You want to put window caulk in a gun? That's a new one on me, unless you're try to blob something on the outside of the window frame... which is a no-no

I'm confused....

Ace has it labeled as Butyl caulk. Others (Home depot, Lowes) carry it as gutter sealant. I have seen white and gray, not sure about black. About $4 a tube. As others have said, tape is easier for windows. Good luck, Raz

If you have the correct weatherstrip for the Uhaul windows you don't need any caulk. The only thing you need to seal up is those two 1/8" drilled holes at the top of the window frame if the weatherstrip doesn't cover them. A little dab of butyl tape will do it, pushed in after the window is installed.

I think that Bob made an important discovery with respect to matching the weatherstrip to the dimensions of the metal window frame and fiberglass opening.

That said, my observation is that the sealing technique on the side windows is just not robust. My UHaul camper came with the original weatherstrips and it leaked. The UHaul repair manual shows how to caulk the side window weatherstrip as a matter of course. Maybe UHaul used the wrong weather strip from the beginning, I don't know. It seems like the rubber cannot correct for irregularities in the sealing surfaces.

So, I can see where Diane wants to hedge her bets. I, too, looked for black butyl caulk and never found it at a reasonable price. I ended up painfully working butyl rope under the outer weatherstrip with Popsicle sticks, patience and much cursing. I still had a leak on the bottom inner seal and I used clear strip-able caulk to test the concept of caulking this area. It worked so well that I have left it for now.

A couple black butyl sources that I found:

Fastenal - these are a franchise and may be local to you. 10.1 oz Black Red Devil Blacktop & Roof Repair Butyl Sealant | Fastenal

Amazon: CRL Black 777 Butyl Rubber Sealant - Amazon.com

I thought I had read somewhere to caulk the window, maybe in the repair manual? Then I read in a thread suggestion to use liquid black Butyl, so I just thought it must be the CRL Black 777 Butyle Rubber Sealent that I found online. I just want to head off any future leaks at the pass so to speak. Have been Plague for so long with these window leaks...And as dry as I try to keep my camper, noticed today mildew on the curtains! Will be switching over to some kind of washable plastic blind.
Thanks you guys.

Thank you Bob & Mary, maybe I am getting too apprehensive...

...For those in Canada, butyl tapes are available with different sizes@ Cross Canada outlets(in my local anyway). To caulk/seal with glue/sillicon...on a trailer exterior/window/roof, this is...WHAT I used to do: Using paper/masking tapes, running parallel each other along where I intend to caulk then take the tape off after all. Hopefully it helps...

What brand of windows were installed in UHauls. We're they Kinro or Hehr? Do they have a frame with overlaping flange outside and a lock ring inside which sandwiches the fiberglass wall? What does weatherstrip refer to in the context of these windows. A lock strip or gasket bead? Butyl tape as a gasket for the overlapping exterior flange? Where precisely is the ingress point of the leak? Between the frame and trailer wall or under the glazing to frame seal?

Jack, Uhaul windows are installed like old time windshields that set in a rubber gasket. The rubber has a groove 1/4" wide that sets over the trailer wall, another groove 3/16" wide that the lip on the edge of the window frame sets in, and then a lock strip goes in a groove in the center to expand it. Tom probably can post a picture, or you can look on perfectfit.com and look up AS1456 to see what it looks like. I have no idea who made those windows originally, they are odd, just like most everything on the Uhauls. If the perfect weatherstrip was made, it would have both grooves 3/16" because that is the measurement of the wall thickness and the window lip. Apparently this dimension weatherstrip was not available when the trailers were made because they used weatherstrip with the 1/4" and 3/16" dimension. I found on my windows, one had the 3/16 groove on the wall, the other it was on the window. Probably because the original installer just did it that way. And one window used a removable lock strip with a pull tab so as to be an emergency escape window, the other window had a fold in type lockstrip. You can see illustrations of both types on that website.

Dunno that a manufacturer has been identified.

The front and rear window have this system which works nicely. The side windows have a H cross section weather strip with locking strip.

The weather strip is this H cross section piece with the lock strip installed (see image below). There is no butyl tape by design.

Water enters either between the wall and the seal at the top, or between the window frame and the seal at the bottom.

I knew Tom could post an illustration much easier than I could, thanks Tom. I'm wondering if Uhaul recommended using a sealer because of the one groove being wider than the window lip or the trailer wall. I don't see in the repair manual where they specify whether to put the 1/4" groove on the window or the wall. I didn't use any sealer other than for the two 1/8" holes, and haven't had any leaks. Someone we camped with recommended ProFlex RV flexible sealant as being good stuff. I got a couple tubes at a RV place, one tube clear, one tube white, and I used some of the clear but don't remember where. Don't remember the price either!
