On Vern's web site I was looking at a car photo which you can make out a reflection of light from under the Roll Bar. On close inspection you can see that he's mounted what appears to be plexi-glass or Lexan to points on the underside and the inside vertical parts of his Roll Bar.
Have any one of you done something like this? If so, What thickness, and what did you use? Lexan? Plexi?
Thanks,
Xack
