Gloss enhancing compositions for polymer surfaces and polishing compositions for stainless steel surfaces are microemulsions of a diaminoorganopolysiloxane, a film forming acrylate polymer, and a wax. The compositions exhibit high gloss, low sling off, and high durability, and can be formulated without organic solvents.
