Duct Tape and WD40!
And way too much other tools. Three boxes in the truck. One with mechanic tools ( screw drivers, wrenches, sockets, hammer, etc... ) second tool box electrical stuff ( multi-meter, pliers, wire stripper, connectors, electric tape, spare wire, ..... ) The third box hardware ( rivets, rivet tool, screws, fasteners, sealant, sealant tape, etc.... )
Also an air compressor, 2 screw jacks, tire wrench, electric drill driver set. I am sure there is more back there. The tool collection has been growing for the last 40 years. Every few years I thin it down a bit, but then think, I might need that some day, and everything ends back in the truck.
