Rant: I tried a new riser sleeve compound on a big gearbox casting and it stuck like glue

Last week at the shop, we had a rush order for a 400-pound gearbox housing. I decided to try that new high-temp ceramic wash on the riser sleeves instead of our usual graphite spray. The pour went fine, but when we went to knock off the risers, they would not budge. I mean, we had to use a cutting torch to get them off, which added about three hours to the job. Has anyone else had a nightmare with a new release agent, or is there a brand you swear by that never lets you down?

Come on, three hours? That's a Tuesday. At least you didn't wreck the casting. Some of these new products just need a heavier coat.

Heavier coat" is code for "we didn't test this enough before selling it.
