Took out the OEM bed liner today to inspect the bed and fix where needed. There was a very small surface rust spot about the size of a penny on the passenger side in the corner but that was it. Gave her a good cleaning then sprayed the high spots and areas with bare metal (from rubbing) with rustoleum gloss black. End result - the bed looks brand new. Cleaned up the bed liner and tossed it back in. Eventually i'll get rhino lining or line X.. its just so damn expensive.
