Twist N Seal Caulk Saver Plug
It's happened to everyone; you get a new tube of caulk or PL, you use just a little bit of it, then a week later when you try to use it again, the tube is soft but the nozzle is rock hard. We've tried all the same lame solutions that you have, the nail down the end, the blue tape wrapped around the end, and all of the other half-assed attempts at preserving the tube.
A company with the odd name of Ultra Mold Technologies has a new product that is a one size fits all version of the caulk tube cap. The way it works is that instead of capping the nozzle from the outside, it's a threaded, tapered plug that can fit inside any tube opening between 1/8" to 7/16". This not only works for caulk tubes but for other things like cans of spray foam.
A package of five costs about $3, but if you buy more than one, the price drops.
Available online at CaulkSaverPlug and a number of traditional stores listed here.
