The bedliner material would be the best for a long term fix but is probably a little pricey. It will evenually need a little "freshening" back to black after awhile anyway. If you don't have the cash for that, try using some foaming tire shine on them. I used to use that but it dosn't last too long.
The best stuff I have found is the detailing spray from the CD-2 engine cleaning kit. It lasts a long time, even after driving in the rain several times.
Hope it helps.
