Those of us who had the previous series of fender trim without the full length reinforcing in the back of them that resulted in them splitting from different rates of expansion between the aluminum lower body panel and the plastic in direct sunlight and had to replace one or both fender trims, here's what we gleaned:
05 previous (original) caulking - Geocel 2300 MHRV vehicle body sealant Pewter #6304
Later number designation was changed to Pewter #0737
contents:
Tetrachlorethylene CAS# 127-18-4
Aromatic Hydrocarbon Cas# 64742-95-6
Thermoplastic-Rubber Cas# 66070-58-4
Hydrocarbon resins Proprietary (colour)
VOC compounds less than 4% by weight
Specifically formulated for Heavy Duty Truck - Trailer Truck body applications including the RV industries.
You can probably still get this stuff via autobody shops or truck repair facilities if you need it.
