Herculiner will work fine. I know a couple guys that have used the Dupli-Color brand roll on stuff too, but they've only been done a few months so I'm not sure how well that brand holds up. I used herculiner for chipguard on my Nissan and it's holding up pretty good after a couple years...this is with daily driving on gravel roads with A/Ts chucking gravel stones constantly.

The trick to getting it to stick and not peel or chip is in the surface prep before you apply it. make sure you do a good job of dewaxing/desiliconing the paint using an acetone type cleaner (careful with this stuff it's nasty!). Next, scuff the area you're coating with fine sandpaper so the coating has something to grab too. Apply as per the can's instructions.

You might want to check with a local Rhinoliner place anyway. There's a lot less surface area than if they're doing a whole bed interior so a chip guard application should be cheaper than getting a bed done. I'd guess you could probably get it done for $150-200...compared to $70 for the DIY stuff and the labor you stick in. Might be worth looking into anyway.
