any experience with the roll-on bed liner?

[68jimmy]

I'm going to be placing a different bed on the 68 and although the bed has some surface rust it is green in color (the 68 is white). I've seen the roll-on bed liner kits and I've priced someone doing the spray-on type. Has anyone used the diy kit? If so how difficult was it and how about the long term wear and tear?

Thanks in advance...
