Used a water bed repair kit to "patch" up the vinyl seat in my buddys sunfrid. Problem was, his seat was grey, patch was teal.
Used an Adidas soccer sock to hold the y pipe up on my Dakota when the hanger broke. I was on a trip, needed something quick.
I used "liquid nails" to re-apply the door molding that half fell off on my dakota. WHen it got hot out, it would slowly peel away as I drove, looking like I had stringy bubble gum holding them together.

The good ole days of bad auto repairs.
