does anyone have experience removing cured epoxy resin from a plastic grip.

bought a P320 module with skateboard tape on it and the previous owner said the tape was applied with epoxy. Holy heck, I have exhausted my chemical cabinet trying to remove the residue from the grip after I removed the tape. Nothing has made a dent:

vinegar
alcohol
citrus based cleaner
acetone
brake cleaner.

anyone have any suggestions or experience with stronger stuff?

thanks

The good news here is it's a Grip Module.
Throw it in the round file and buy a new one.
There are many new ones, the Wilson Combat one I hear is good.

Yup.  About $35 for a factory replacement.   Just buy a new one and use the old one as a paperweight.

The curing reaction of epoxy is not reversible.
And there is no solvent for cured epoxy either.

You can break it down/weaken it with certain solvents.
IIRC we used to use hot MEK to dissolve printed circuit boards.

After we purchased a decent x-ray system we used that to examine internal layers of boards.

It took some interesting tricks to examine smaller structures.

Aircraft grade stripper. It’s nasty to deal with, but might work.

We used to dissolve epoxy potting on electronics with warm MEK.

There is a decent chance it will ruin plastic grips though.

It is also a very dangerous thing to do with a setup that heats the
MEK by circulating hot water in copper tubing to heat the MEK up.

Epoxy curing is pretty much a one way thing.
There is no solvent, just aggressive chemicals to break it down.
