Abstract : The present invention relates to a method for preparing a titanium or titanium alloy surface and a primer for use in the method. The method broadly comprises the steps of grit blasting portions of the surface to which an adhesive will be applied and thereafter applying an acid wash primer to the surface portions. The acid wash primer preferably consists essentially of 70% by weight isopropyl alcohol, 5% by weight ethyl alcohol, 15% by weight n-butyl alcohol, 5% by weight zinc chromate and 5% by weight phosphoric acid.
