A4 exterior door trim replacement

[rocketscienceracing at comcast.net]

The stupid black exterior trim pieces at the bottom of all 4 doors are starting to fall off. It appears the clips are good, but the trim is rotten. I had heard that this trim was prone to early failure. I would consider it early as my car is a 98.5 with only 80K miles.

Although it appears straightforward, any BTDT, tips, hint, tricks, experiences, etc. with regard to replacing the trim would be most appreciated.

Thanks!
