Our Ace is going out of business and I was there getting a bunch of bargains at 50% off. I noticed they had tubes Butyl, the type that goes in a caulking gun. Never one to pass up a bargain I bought all they had. My question is, can I use this on my windows? I was thinking, and this gets me in trouble frequently, If I were very careful I could lay a bead around the flange and install the window. Anybody ever used this type butyl?
Thanks,
Mike

Mick, I really think you need to use either putty or butyl TAPE. The reason tape is used is because it will release if the window needs to be pulled/repaired. Caulk makes a mess of things on metal flanges and tends to fail.
The butyl caulk may work on roof protrusions if it is similar to Dicor self leveling lap sealant. The self leveling part means it seeks nooks and crannies when leveling.
Most of us use very little caulk on our trailers. Please let us know the brand and purpose of what you bought so that we can share ideas.

I'm reading between the lines here but from what your saying there's more control and less seepage with butyl tape? With heat and or the pressure of seating a window, door or whatever you're apt to have excess "squeeze out" that you wouldn't have with the tape.
The brand is Ace's own and its says the application is wood, concrete, or anywhere moisture is a problem. I might come across a use for it, or not, but it was too cheap to pass up.

Well, sort of:
We don't use caulk to install windows, vents, doors, anything with a metal flange. Putty and butyl tape are much better and last for many years. Repairs are easier with putty and there's hours less scraping and picking to do. If the skin has a pattern (dips), putty is great for filling gaps.
There are many uses for caulks, from filling holes underneath the trailer to sealing roof protrusions, depending on the purpose. Some of us use Gutter Seal (in a toothpaste like tube) for a very THIN SEAL on the top of the J- rail to keep the putty from drying out and to provide extra insurance.
Caulk and sealant operative words are THIN, SPARING AND INVISIBLE. There will be uses for the Ace caulk for sure. If it is truly butyl, it should be fine on the roof. There are two types of butyl: self leveling and Non sag. Non sag is used for vertical applications where runs aren't welcome.
I'm the same way; can't pass up a bargain...
