I am writing this after seeing the GP on the fillers. Seems only the Buicks are the ones that don't seem to last as long as other makes. I paid over $400 for my car a few years back. Anyone ever wonder why the fillers on their cars deteriorate after awhile? I'm beginning to think that Buick screwed up on the formulation of the filler material. I had an 85 Olds Cutlass and the filler was pristine all the way until two years ago when I gave the car away because I got another car. The new owner still has the car and the fillers still haven't deteriorated! Maybe someone knows the real answer to this one.
