solvent for JB weld
wellp, had to happen sooner or later. i bought a product that has some sort of super-stuff on it, most likely JB Weld. too light in color for liquid nails, might be 1 of those 2 part epoxys.
anyone know of a solvent that might loosen (doesn't need to totally dissolve, i'll settle for softening) up some of these super-goos without damaging/attacking the aluminum? lost finish/color, i can deal with, structural damage/pitting, i cannot.
i've tried so far: acetone,
trichloroethane (parts washer stuff),
any other ideas?

Maybe the two part solution Brute and Force?
You used some pretty harsh cleaners on it and its still not budging. Got any pics of the compound?

There are no solvents I know that will penentrate after curing.
(J-B Weld is water soluble before curing, others can be either Benzine or Zylene based)
1-1-1-Trichloroethane is perhaps one of the real solvents you list having tried (don't let it contact copper, the ions catalyze it and turn it from flammable to combustible) but other strippers can contain ketones as well as esters.
Once the stuff has dried, the valance level of the molecular structure make it damn near impervious to chemical decomposition similar to plastics used to store high-strength acids.
The only thing I can suggest is heat, but I would be skeptical about trying to bring the material temp high enough without resulting in annealing the metal beneath. Aluminum can handle higher temps than brass since it goes through a transition phase known as "normalizing", but even that may not be high enough to break down whatever you have stuck to the thing.
Based on all that, which is just my opinion from empiric experience, if it were me I'd go straight to a mechanical solution, which is to grind it off with a Dremel or similar tool.
<edit to add>
The pics were posted as I typed that~ I would say if it were myself, the time/effort used in trying to clean THAT up would be higher than the cost of a new barrel.
