Mud in the eye

For the last couple of races I have been challenged by mud coming through the gap where the windshield used to be, or actually still was, leading to dramatically reduced visibility. I have been thinking how I can get around this and after watching a few NASCAR races where they have tear off windshields I have come up with the idea of a tear off for my helmet visor. Naturally as I dont have the budget of NASCAR I have crafted my tear offs from as an artists would say "found objects." In this case duct tape and the clear fronted Priority mail envelopes. I think its gonna work. If it gets covered in mud one pull of the duct tape and it's gone.
