Contact your local Dow Corning rep., they have a product 'OS20 fluid' that can disolve cured RTV. I have used it with good results. It requires 12-24 hours min. of soak time.

When you talk about a cured polymer, it needs more than a just a solvent to dissolve it, you must actually break the bonds of the polymer, and destroy it, and RTV is some tough stuff.
