not sure if those emblems are aluminum,in my 78k they were gold anodized aluminum but i sanded them,with an electric orbital sander fine grit,120,then 400 grit then 2000 grit and buffed,background of emblem was painted semi gloss black,they look chrome now, no more gold,when you paint the background you will have to carefully wipe the buffed raised letters with paint thinner to remove the paint,buff again carefully,,,i love aluminum
