Sorry I didn't say it better, but my thought on the bedliner was to apply it on top of the foam to help it last longer . . . .

However, I haven't seen any wear in the canned " Great Stuff' " that I applied a couple of years ago when I upgraded to dual shocks on the front.

OH, ok...great!! That's a nice idea...not sure how well it would stick to the foam since the two don't have similar expansion/contraction/flex properties.

that foam has been on mine for 20 years. not sure it needs anything to protect it.
