How to remove cured epoxy?

[Stalldog]

How do I remove cured epoxy from aluminum? MEK? I've tried acetone with poor results. The instructions on T88 say to use paint stripper. Would that be the same as MEK?

If the alum was not prepared for bonding the epoxy, like sanding or scuffing with a scotch brite pad, they you may just be able to chip it off with a plastic scraper or something similar.

It's actually some spots here and their on the rudder skin, left over from gluing the trailing edge. Had some on my fingers and, well you know the story! Anyway, acetone seemed to VERY slowly eat away at it, but if something works faster I'd like to try it. I do have a plastic applicator that I used for the epoxy that might be stiff enough to try and pop the epoxy loose. Skin wasn't prepared or anything, but T88 seem to be pretty tough stuff.
