An anti-fouling composition which comprises a cured or cross-linked polymer free of perfluoropolyether moieties and a fluid fluorinated alkyl- or alkoxy-containing polymer or oligomer. Preferably, the fluorinated alkyl- or alkoxy-containing polymer or oligomer comprises a repeating unit of the general formula:—{[CFR—(CFR)—(O)]—[CFR—O]}—wherein n is 0 or 1, m is an integer from 0 to 4, R independently is H, F, Cl, Br, or CF, and the ratio q/p is 0-10, and the fluorine-free polymer is an organosiloxane-containing polymer comprising a repeating unit of the general structure —[SiRR—O]—, wherein Rand Rare independently hydrogen, alkyl, aryl, aralkyl, or a vinyl group.
