PURPOSE:To obtain the title primer compsn. based on a silicone resin which is excellent in weathering resistance, by incorporating a wet curing silicone wax with at least one member selected from among mercaptosilanes and aminosilanes, or at least one member selected from among glycidoxysilanes and mercaptosilanes. CONSTITUTION:100pts.wt. wet curing silicone wax based on a polysiloxane having at least two hydroxyl groups in its molecule and a silane compd. having at least two alkoxy groups in its molecule is incorporated with 1-20pts.wt. at least one member selected from among mercaptosilanes and aminosilanes, or at least one member seleted from among glycidoxysilanes and mercaptosilanes, to thereby obtain the title primer compsn. Preferred silane compds. having at least two alkoxy groups in their molecules are those having two or three alkoxy groups and the preferred alkyl is methyl or ethyl from the standpoint of curing rate.
