Are you kidding about JB Weld?
I once was following an older buick that threw a hub cap at about 40 miles an hour in town here. The hub cap rolled across the street, hit the curb and became airborn just in time to partially sever the head of a 12 year old boy walking down the street.
The paramedics said that if it wasn't for the quick thinking of that old Buick driver and the application of the quickset JB Weld to that kids neck he never would have made it...
When in doubt use just a little more....
