This is the only instance I use Talc, in the form of a cheap baby powder I bought at The Dollar Store.
I had found out that when I patch a tube, later I'll sometimes see the tube stick to the tire at the patch/tire contact. Now, after patching tubes, I'll dust that junction with baby powder, and no stickiness again.
