PRIOR TO VACUUM METALLIZING, SHAPED ARTICLES OF THE COMPOSITION ARE IMMERSED IN AN ACID BATH. THEREAFTER THE ACID TREATED ARTICLES MAY BE VACUUM METALLIZED AND A PROTECTIVE TOPCOAT APPLIED. AS AN OPTIONAL PREOCEDURE, THE SHAPED ARTICLES MAY BE COATED WITH A PRIMER OR UNDERCOAT AFTER TREATMENT IN THE ACID BATH AND BEFORE VACUUM METALLIZING.
