blue painters tape image by Jim Mills from Fotolia.com. You can transform the appearance of your chrome grill by refinishing it with the right kind of paint. Because metallic grills are nonporous, they are ill-suited for adhesion. Condition the grill to accept paint by abrading it.Unfortunately, chrome grills are too durable for the same friction-based abrasion methods used on vinyl and plastic surfaces. Instead, apply a special acidic primer that will etch the grill, otherwise you will ultimately end up with heavy chipping and peeling.ait two to four hours for the grill to dry. Cover portions of the chrome grill you do not want painted with painter's tape. Cover the surface beneath the grill with drop cloths. Coat the chrome grill with etching spray primer. Hold the can about 8 inches from the grill as you apply.
