Yes, the silicone along the sides is the easy part... this butyl stuff alone the bottom is like a rock though, and i've heard it sticks to paint better than paint sticks to the car...I can just forsee a giant sheet of paint coming off with the butyl glue along the whole base of the glass... I thought about using a wire to "cut" it out, but the way it sits against the ridge on the cowl, that too would likely chew up the paint pretty bad... maybe I should learn to live with the windshield that's already on it... (can you tell I'm trying to talk myself into letting well enough alone? )
