Abstract
A method is provided for end finishing an elongated composite trim strip. The show surface of a strip is first coated with a mask material. The strip is then cut so that the mask material covers the show surface adjacent the cut end. The end is painted and the mask material peeled away taking with it any excess paint and providing a clean edge between the painted end and the strip's show surface.
Claims2
A method of end finishing a composite elongated molding strip comprised of a first polymeric body portion and a second body portion that is readily visibly distinguishable from said first body portion at a cut end, the method comprising:
- coating the top surface of a said strip in the area to be end finished with a peelable elastomeric mask material;
- cutting said strip in said coated area to reveal a cut end, the top surface adjacent said cut end being protected by said mask material;
- painting the cut end to conceal the visual contrast between said first and second body portions thereat;
- and
- thereafter peeling said mask material from the strip surface, thereby removing any excess end paint and providing a well defined edge between the painted end and the top surface of the strip.
A method of end finishing an elongated trim strip formed of a polymeric material coextruded with a metal foil, said strip having a contoured decorative top surface, the method comprising the steps of
- applying a molten layer of a peelable polymeric mask material to at least the top surface of the strip portion to be end finished;
- cooling said layer until it solidifies;
- cutting said strip such that a desired end contour is formed and such that said mask layer covers at least the decorative surface of the strip adjacent said cut end;
- applying a finish coating to the cut end;
- and
- peeling said mask material from the strip surface thereby removing any excess finish coating adherent thereto and providing a clean edge between the decorative strip surface and the coated finished end.
