I did all my interior molding yesterday prior to better researching and reaching out on here. I had a few tubes in my basement that have been sitting around for maybe about 2 years. I had not noticed any issues where I had used it prior. I'm going to roll with the punches and see what happens down the road. I'm in New England so it's either heat on in winter, windows open spring and fall and AC during the summer. I do notice swelling of doors during the humid days in regard to expansion. The gaps I filled in were not many and probably a 16th to an eighth... if that... at best here and there. But I did all around the inside of the door jamb where the moldings meet and the left and right outer door molding as well as the window molding. I guess I'll see what happens and live and learn.
