Following up on this, even after all that baking and cooling, there was a little residue on the 
guides after the reels passed. The residue seemed to come much more off the back-coat side -- very 
little of anything on the heads or takeup guide but some crud on the supply guide and pinchroller. 
Not enough to gum up the works but more than would be expected from one pass of a good tape. Got a 
good transfer so hopefully that's it for these tapes. Made a safety dub at the same time, onto 
supposedly "cured" Quantegy 457. Check back in 10 years and we'll see if it's really cured.
