They say duct tape fixes everything. While I don't know who "they" are, I do know they're wrong. Try fixing a leak in a radiator a 100 miles from home on a Sunday with duct tape. Won't happen. And the Amish don't sell eggs on Sunday, so adding eggs to the radiator wasn't and option. (yes that really works)What does work on Sundays, and every other day, is one of these handy epoxy packets, and with the variety pack, you know you've got the right one for the type of material you're repairing. (in this case, it was the plastic top portion of an old Camry radiator)It got me not only home, but lasted for months until I sold the car. I like to think it's still holding, and yes, I did inform the new owner of the repair.This is AWESOME stuff! And so far, it's not on the TSA confiscation list, so don't tell them about it, they'll just steal yours.
