will absolutely ruin the paint on your LU and those with the two rubber contact pads on each side can really stick sometimes. I've tried the two styles and have chosen to use the kind I'll call 'Duck Bill' type. I cut two strips of 2" wide Velcro loop with the sticky back and put a strip on each of the sides of the 'V' of the duck bill and it will no longer stick when you lower the LU and it will not scratch the paint..................G
