I purchased the one piece trunk weatherstrip from honda parts unlimited, but before I install it I was wondering if any of the experts out there had any tips for me so I don't screw up as I'm new at this. Right now I have the original weatherstrip which is 17 yrs old and I figure it got compressed over the years as the trunk gets some pretty bad leaks after a downpour, with water collecting in the well behind the brake lights on the trunk lid as well as in the trunk itself? Any advice?
Thanks!
