All these threads turn into streams of two kinds of posts: "I used Monokote the other day and it was bad" or "I got good results so you people don't know how to use it." I've gotten some very good results and some very bad ones. The key seems to be whether the roll you got stinks when you open it. If it doesn't, you'll be fine (though it shrinks somewhat less than it used to: as mentioned earlier, better to use an iron than a gun on open areas). If it smells bad, you'll have a problem; sometimes in applying it (a problem I personally haven't had yet) and sometimes in sagging and wrinklng after it's on. I like good Monokote better than any other film, but the others (Ultra and 21st Century film) don't seem to have the QC problems that Monokote has. For me, it comes down to whether I'm feeling lucky (as well as what colors are available).
