It looks absolutly great but as previously stated paint or some other form of finish is needed. Consider spray on bed liner, or mabybe even better look into plast-dip. It's a product to dip your tool handles in to give a sturdy plastisized coating to get the rubber type grip like the more expensive tools. Using a plastic coating it will give a nice finish, not to mention the look of a customised factory type finish which will always lead to the what company makes this . You already have a real nice design but with the application of a industrial manufacturer look you could have a marketable product sold individually or through chain stores (Auto zone, napa, checker). But by just first look you could have a money making product.
Just my $.02 cents worth.
