Steven,

I've used my commercial Hot Air gun on the face of some of my lithos
to remove some harsh edges to soften and blend its appearance when lit behind.
Also a light coat or two of clear sealer helps smooth out the grainy surface,
without diminishing the lithos detail. ---- "No Torchs Involved"

Yes, a heat gun I can see. You get the heat without the flame. It seems like a flame would give you results you would not want; i.e., carbon residue, melting, etc.
