PSA: that creosote log you burned just coated your flue in glaze
Last Tuesday I ran a service call in Wichita on a customer who swore they swept their own chimney with those chemical cleaning logs twice a year. I stuck my head up there and my brush bounced right off a hard, black, shiny layer about three feet above the damper. That stuff is basically glass, it chips off in chunks and blocks the smoke path. I spent two hours with a rotary chain knocker and still had to come back the next day to finish. The homeowner asked why the log didn't work, and I told them it just turns the creosote into a solid sheet that hides the real buildup underneath. Has anyone else dealt with this glaze situation, or do you guys just refuse to touch flues where those logs were used?

turns the creosote into a solid sheet" is spot on, but it's not really hiding buildup so much as becoming its own nightmare. That glaze is worse than the original creosote cause it's basically impossible to brush off, like trying to scrub a ceramic pot. I've seen it flake off and jam up dampers too, so you're not wrong about the smoke path thing.
