Stus-List Hatch rebuild - removing silicone?

[Dave S via CnC-List]

Good evening all,
Have my Bomar hatches disassembled and have found an anodizing shop to
refinish the cast aluminum frames.   For the anodizing to be perfect,  the
silicone must be completely stripped from the frame.   This is proving to
be a bit of a hassle.
Does anyone know the magic or magic solvent that will dissolve this
lovely/unlovely stuff?
Thanks, Dave
