If one was going to remove and recaulk window frames would you use 3M 3000UV or 4000UV. It seems like the 3000 is a lower strength version of the 4000 in case you needed to remove a window.

I have used butyl tape in the past and regardless of running a bead of caulk the tape ran.

Thanks

"the tape ran"? what's that mean. What color tape did you use?

The tape was gray. After the butyl tape we ran a bead of caulk and on a hot day the butyl tape would push out from under the caulk.

I have never heard of doing both caulk and butyl tape. The benefits of using tape are lost once you combine it with caulk. I guess I don't understand why.

Sounds like you don't want to use butyl tape again from the experience. I liked it because install was easier. It does need some time and hot weather to fully bed and tighten the frames. White or grey should help with any bleeding that does happen if not fully tightened.

Was following Diamond Seaglaze directions. I think the caulk was intended to keep the butyl tape from "running" and provide a finer finish.

Butyl tape is often used with caulking , just added protection to keep water out. Used it like this in commercial construction. Worked great on resealing windows on Pointer . Also ,any uv protected caulking , with white butyl tape .
