I've had no bad reels of Maxell or TDK, but I haven't had that many of them. 
And you can be sure that 457 will turn to glue if it hasn't already. I don't 
even trust the stuff they made later in the 80s when they'd supposedly solved 
the problem..I have a lot of reels from Drake Chenault that a radio station 
tossed in the early 90s, and there's no way to tell when it was manufactured. 
Some was sticky when I got it, some was fine, some that I thought was fine a 
year ago is beginning to develop SSS. All back-coated Ampex is suspect if it's 
more than 10 years old, in my opinion. You don't have to bake it unnecessarily 
though..just run it outside the tape heads in fast forward and run it through 
your fingers. You'll know soon enough.
