I've used a bottle opener many times to remove drip rail stainless. Just start at one end and work towards the other end. If it is 2 piece, start at the far end of the piece that overlaps the other one. Using a rag at the top end helps keep from scratching or denting it. I have also removed it with Channel Locks and a rag. To install it, I just start at an end and hook it over the top edge like everyone else does and pop it in place with the bottom of the palm of my hand.
Do you know there's 2 different sizes of drip rail stainless trim? The kind for a vinyl top car has a green stripe on the inside of it and the non vinyl top trim does not. The vinyl top trim is ever so slightly bigger because the vinyl is trimmed to fold over the top edge of the drip rail when it is installed and glued into the drip rail.
