That was me over on pontiacbonnevilleclub.com.
I had a 1997 Bonneville SE that I kept in like-new condition; owned that car from 1999 to October 2015 when my wife totaled it.
But we also bought a 2001 Grand Prix GT in 2003 for my wife, and sold it in 2010 when we got a minivan for the kids.
The neighbor I sold it to got a newer vehicle this summer and *gave* the Grand Prix back to me. When I got it back, it had a lot of issues that needed to be deal with, and you can read my thread about its resurrection here: http://www.grandprixforums.net/threa...-Grand-Prix-GT
I did a lot of searching for a material to replace those brittle door trim strips with, including pulling them at a salvage yard, but they're just too brittle and shatter if you look at them. That rubber edge-trim is really the best option out there to replace that trim, and it's pretty cheap. It ships in a coil and has a bit of shape-memory to it, so heating it with a heat gun or letting it lie in the sun for a while is really good to get it to warm up and relax the coiled-up shape. I don't think the bead of glue along the inside really does very much, but the fit of the trim is nice and tight, so it stays in place really well.
