i have a '95 4runner. one of the things i was planning on doing to it when time and a college budget permits is duralining the bottom 12-14" of body- much similar to the white and tan 80 series on the ih8mud classifieds. any advice on doing this yourself would be appreciated. also, lots of people who use it as bedliner generally apply it straight to the bed with no more prep work than washing it out really well- how important is sanding down the old paint with this stuff? thanks y'all
