A sliding engine component having a sliding surface provided by a plastic polymer-based laye on a metallic substrate (102), wherein the plastic polymer-based layer comprises a plurality of plastic polymer- based layers (104A, 104B), and is obtainable by the process of: depositing a first coating of a first polymer-based layer (104A); curing the first polymer-based layer at a first temperature; depositing a second coating of a second polymer-based layer (104B); and curing the second polymer-based layer at a second temperature that is lower than the first temperature.
