Geocel Pro Flex Failed.

Question

So first time using this stuff, removed all the moldings from a large window 4x4, and resealed it using 2 tubes of this stuff, put it on quite thick to fill the channels. 9 days later i went camping, when i pulled into the campsite, the rear window was hanging against the ladder, ripped clean out of the frame.

all the geocel, was soft, like wet bubble gum, i could rip it clean off with my hands.

does this stuff not harden up at all? i am going to have to go back to the molding insert i guess, at a ridiculous markup, but it beats hot gluing it back in to get it home.

so the question.. how hard does geocel get, as i bought 3 more tubes to do another window, but now i'm scared to use it.

Wrong application for that caulk.  It doesn't cure for a long time in an enclosed space, that is why it isn't hardened while still in the tube.

I assume from your post you pulled the actual glass insert and then attempted to install with the Geocel. Doug

Dougi removed the outside weather strip that had failed.and filled the gap.i have found some molding that will work, but it's over 5 dollars a foot, its going to cost me close to 300 to replace 2 window seals. Doug do you have a link to the sealed window(non sliding ) that will work that may be cheaper, or is it really 5 bucks a foot?

I am not sure exactly what you are doing but if the window was removed and reinstalled the proper material to use in the channels is butyl tape.  Do not use plumber's tape by mistake.
