Yes, first you insert a full tube of the caulk in the crevice, and then open another tube and get out the drywall knives to smooth it after you glop it all ontop of the other caulk tube backer rod LOL!!
We've used it and have had great luck with it. I tried it on one of the rooms in my basement when i remodeled it to fill nails holes/tight up joints, etc.. and thus far..it really does stretch and has'nt cracked yet....works great with installing replacement vinyl windows/new construct vinyl windows too since silicone does'nt stick to vinyl.
