Molding the Bumpers

I was wondering what it takes to mold your rear and front bumpers??? How much would this cost?? Anyone think it be cool to mold my oem bumpers?? I love the stock accord look and will not get a bodykit maybe xenon rear valanve and side skirts an a greddy front lip so it wouldnt matter if I moldede the bumpers since those just replace my allready existing lips.
