I was coming out to my truck and saw something leaking under the bed. I opened the tool box and The bottle of coil cleaner had leaked and ate a 2 inch diameter hole in the bottom. I got home and unloaded the bed of my truck and the tool box. No easy task. The bed was OK the fluid was leaking out one of the drain holes. My oxy/acet set had fallen over on it and punctured the bottle.
