  • MASKING ARTICLE
    Publication number: 20080118656
    Abstract: An elongate masking article (3), suitable especially for removable-attachment to a vehicle for masking a gap (15) between two relatively-movable parts (16, 18) of the vehicle, has an elongate transverse cross-section and is so constructed that an enclosed space (10) can be opened up within the article by applying pressure on opposite sides (6, 7) of the article to reduce the length of its transverse cross section, whereby the article is able to deform to fill the gap. The enclosed space (10) may be located between two layers of material that are arranged face-to-face and joined together along the said opposite sides (6, 7) of the article.
