This invention concerns a spray can. The spray can comprises (a) a water-repellent surface treating agent composed of a polyorganosiloxane represented by the general formula, HO[R.sub.2 SiO].sub.n H wherein R denotes a monovalent substituted or unsubstituted hydrocarbon group and n a numeral of the value of 5000 to 100,000, and possessed of hydroxyl groups one each at the opposite terminals thereof and a silane coupling agent, (b) a silicone oil as a freezing property improving agent, (c) .gamma.-aminopropyl triethoxy silane as a silane coupling agent, (d) dibutyl tin dilaurate as a catalyst, (e) a mixed solvent consisting of 1,1,1-trichloroethane and 1,1,1-trichloroethylene and used for the dissolution of the composition of the components (a) through (d) mentioned above, (f) Freon R-12 as a solvent capable of assuming a gaseous state at room temperature under atmospheric pressure and used for addition to the aforementioned mixed solvent, and (g) a can body to be filled with the components (a) through (f) mentioned above.

Spray can

There is disclosed a weather strip which comprises a metal insert of W shape in section and a covering member adapted to cover the insert and made of polymeric resilient materials. The insert is formed from a metal piece which includes two longitudinally extending primary portions in parallel relation, and a multiplicity of secondary portions each having a connecting portion interconnecting the primary portions and two projecting portions extending outwardly from opposite ends of the connecting portion. The projecting portions are bent upwardly and preselected connecting portions are cut off from one of the primary portions and are bent upwardly at right angles substantially from their centers.

Weather strip

A colored weather strip attached to a flange on an automobile body defining a door opening. It has a sealing portion, and a U-shaped trim portion formed from solid rubber and joined integrally with the sealing portion. The trim portion has an outer surface covered by a colored solid rubber layer having a color which differs from those of the sealing and trim portions. The colored layer extends beyond the trim portion to cover a part of the outer surface of the sealing portions up to a point close to but not into the area where the automobile door contacts the sealing portion.

Colored weather strip

A metal carrier is embedded into trim, for providing proper rigidness in the transverse direction as well as in the longitudinal direction to the strip-like trim formed with rubber or plastics and the like. Transverse slots are formed in the strip-like sheet metal at given intervals in the longitudinal direction and a thin link portion and/or narrow width portion (sectional area in the transverse direction is small) is alternately formed at the top and bottom portions of the transverse slot. When an external force is applied to the metal carrier covered with rubber or plastics, the formed connecting links of the thin link portion and/or narrow width portion at top and bottom are broken, and the metal carrier becomes a continuous zigzag strip.
