There is provided a method of treatment including (i) applying a treatment composition to at least a portion of the surface of a wheel rim and (ii) allowing a thus applied treatment composition to cure. There is also provided compounds and compositions useful in the method.

Method for treating wheel rims and composition for use therein

The present invention provides a combination filter for filtering fluids comprising a flow channel particulate filtration media having a first face and a second face and a gas adsorbing filtration media. The flow channel particulate filtration media comprises a plurality of flow channels directed in flow direction and defined by inner surfaces. The flow channels having inlet openings through the first face and outlet openings through the second face of the flow channel particulate filtration media. The inner surfaces of said flow channels at least in part are provided with structures protruding therefrom and forming or extending into the flow channels or an electrical charge or a combination of both. The said gas adsorbing filtration media comprises a pad having a first face and a second face and width and length dimensions orthogonal with respect to each other and each individually to the flow direction and having a thickness dimension in flow direction. The pad comprising a layer extending substantially perpendicular to the flow direction across the width and length dimensions of the pad.
