PURPOSE:To enable to apply a sheet at a position more accurately than ever by a method wherein positioning marks painted with heat resistant paint onto the outer surface of the hardened surface layer of a prepreg sheet in a manner intersected each other at a predetermined angle. CONSTITUTION:A prepreg sheet 20 consists in laminating a bonding layer 21, a resin layer 22 and the glass wool hardened surface layer 23 one upon another. The positioning marks 24a and 24b, which intersect each other at right angles, are painted with heat resistant paint onto the outer surface 23a of the hardened surface layer 23. Because the marks 24a and 24b are painted with heat resistant point, no melting-out of the paint occurs in a coating oven even under the condition that the prepreg sheet 20 has been sticked to the car body before a painting process, resulting in giving no bad influence on the existing painting facilities. |
