I have these in spots all over the car - in the doors, door jambs, front fenders, trunk - they were put in after rustproofing at the dealership-(I'm pretty sure) saw an article in MCG years ago on it - still have it somewhere - but I'm sure these will break- or at least some will when I redo the car - does anyone have any idea where I can get new ones/or maybe someone has a stash , it says TUFF KOTE DINOL inside of a triangle - thanks in advance for the help, Joe
