Autozone - Plastic Epoxy (2-part tube) $5.95
1/2 PartA, 1/2 PartB - the container has a "plunger" that allows both parts to be dispensed onto (e.g.) Cardboard and any stick (e.g. toothpick) can be used to stir well., at which time it can be carefully and evenly spread thus filling the imperfection and ensuring (to soothe your irrational paranoia) that there will be no "bare metal" (or whatever).
Epoxy can be purchased at any Retail Auto Parts Outlet, Hardware Store, or even probably Kroger's. I do believe you can find it at (OMG!) Dollar Stores. I've used it many a time in Autobody Repair (yep, and I can paint them too). I've also used it to repair a (OMG!) Home Appliance (dryer).
Your buckets of arguments still leak... Are you relation to Piers Morgan?
