These are things handed down from a old wise fix-it up genie... or that is what I have heard anyway.
There are only 10 things in this world you need to fix any car, any place, any time. 1.) Duct Tape: Not just a tool, a veritable Swiss Army knife in stickum and plastic.  It's safety wire, body material, radiator hose, upholstery, insulation, tow rope, and more - in an easy to carry package.  Sure, there's prejudice surrounding duct tape in professional competitions, but in the real world, everything from Le Mans-winning Porsches to Atlas rockets and attack-helicopters use it by the yard. 2.) Vice Grips: Equally adept as a wrench, hammer, pliers, baling wire twister, breaker-off of frozen bolts and wiggle-it-til-it-falls-off tool.  The heavy artillery of your tool box, vice grips are the only tool designed expressly to fix things screwed up beyond repair. 3.) Spray Lubricants: A considerably cheaper alternative to new doors, alternator, and other squeaky items.  Slicker than pig phlegm, repeated soakings will allow the main hull bolts of the Andrea Doria to be removed by hand.  Strangely enough, an integral part of these sprays is the infamous Little Red Tube that flies out of the nozzle if you look at it cross eyed (one of the 10 worst tools of all time). 4.) Margarine Tubs with Clear Lids: If you spend all your time under the hood looking for a Dodad pin that careeneed off the whathamakalit valve. When you knocked both off the air cleaner, it's because you eat butter.  Real mechanics consume pounds of tasteless vegetable oil replicas just so they can use the empty tubs for parts containers afterward. (Some of course chuck the butter-colored goo altogether or use it to repack wheel bearings.)  Unlike air cleaners and radiator lips, margarine tubs aren't connected by a time/space wormhole to the Parallel Universe of Lost Dodads Pins.
No thanks needed.
I hope this helps in your repair endeavors...
