i just tonight took off two drip rail chrome pcs by grssping the under /inner edge and slowly lifting and rolling until i worked all the way up,,,came off nice..give it a try,,,
When I remove them I usually put a layer or two of masking tape and use a bottle opener very gently to remove the trim. Use the blunt ended side of the bottle opener.
Hmm this thread here? Drip Rail Removal Tool
