I think plasti dip is probably best bang for your buck. Since you mentioned de-chroming your limited, check the link below. I put the front and sides on mine last spring and have been happy. The vinyl comes in a big sheet with the pieces pre-cut, I had plenty leftover to do the bumper trim piece and could have done the garnish too but i'm happy with the black overlays it has on it now.
