I'm thinking about replacing the hood pad on my 1986 2.3-16V. I understand about the INSTALLATION procedure, but what about the REMOVAL? Seems like the (open cell) foam will have deteriorated over time/temp and will come off in chunks, slabs, and pieces. Did anyone cover their engine bay with plastic to prevent the s@#$ from getting in? Or will the pad come off in one piece with no "hangers-on"? Does one have to scrape residue off the hood with, say, a plastic putty knife? More "removal/cleaning" insight would be appreciated.
