Not Very Good
February 1, 2012
First, these are not clear. They are white (and slightly translucent). Second, these are very rigid. You would think that they would be soft considering what they are supposed to do but that is not the case. Though they might protect the paint on your garage wall, they are definitely hard enough to chip the paint on a car door.
A day after I installed them in my garage, both warped and now neither sits flush against the wall.
Overall, this was a big waste of money for me.
