I am in the automotive trade....lots of my friends have panelshops/mechanical repair shops both here and in japan...i usually get called in for one off jobs,jobs that require attention to detail or jobs that require a bit of engineering/design for componants that have been damaged,failed/have a design fault or are no longer available so therefore have to make the part in question,basically all the ball breaking jobs .......sometimes i am asked to fix the unfixable...i usually do something starting with the letter "F" to it and it aint fix
