This Forum Is Great... One Big Crossfire Think-tank!!! danimal My Valve Stems Are Missing At Least Once A Month... Always In Parking Lots... People Steal Them!!! I've Gone As Far As Putting Vaseline On Them Once To Make It Grimy And Slippery... Boy Does It Collect Dirt...but... As I Figured It Didn't Stop Them However... I Know They Said To Themselves ... They Twisted It Off... What Da F@#k Is This Gooky Stuff??? Hehehe... These Locking Spin-caps Are Great!!!
