Seems there are some people here who might have an answer to this.
What can be used to dissolve *cured epoxy?
What can be used to dissolve a thin film of cured polyimide.
Unfortunately, the maker of the polyimide thought I was nuts for
wanting to dissolve it and told me that nothing will dissolve it.
OK, if nothing dissolves it, what will de-link it? *Will UV light do
it?
Could strong UV light be used to soften epoxy so as to be able to get
better adhesion to a later layer?
I'm not sure what you are doing but common paint remover which is made
with lye, I believe, will softer polyester. Not sure about epoxy.
However it is probably not something you want to use as it is
difficult to control. I discovered this fact by attempting to remove
some paint from a hatch cover. Suddenly things got soft. I scraped off
the softened resin and washed it several times with water and the next
day it found that it had re-hardened.

I have tried every gawdawful chemical I can think of up to and
including Hydrofluoric acid. I do not want to touch the metal surface
underneath.
