Yeah do the bumpers silver. That would look awesome. I really like the scheme of the longhorns, but I don't care for the gold color of the lower half.
Just an idea...Brad (Thor09) recently did his chrome bumpers with plasti-dip, then used the glossifier for plasti-dip. Then he sprayed over that brilliant black (to match his truck). So he could potentially peel it off if he wanted to, but it looks VERY close to a perfect color match...and it cost him just the cost of the paint. I think they have the silver color like what your lower half is in a Duplicolor paint that runs about $7/can. He did both his bumpers this way as well as chrome door handles, and so far they are holding up great.
