Almost none of it is. ABS is one of the most common plastics, but
you'll find others, including PVC, glass-filled nylon, polypropylene,
HDPE, and more.

If it's a really small area I've sometimes tried stippling with a fine
brush after applying a tiny amount of solvent, or "ragging" it with a
wad of suitably textured cloth (wadded into a ball and applied like a
stippler). Perhaps it's just my lack of skill, but I'd describe the
results as disguises rather than matching repairs.
