1)if you drop a bolt,nut screw,tool ect.,just let it fall and watch it,don't try to catch it,cuz you won't,you will fumble it bounce it off your car or knock it to that place where things go to never be found,and it still fell,just let it go and you will see where it is,dropped a wrench,tried to grab it and it bounced of my hand into my car,luckly before paint 2)if you need to put several extensions together,like reaching through trunk,tape them together so they wont pull apart 3)grease in a socket will hold a nut in place when going on a tight vertical spot 4)wrapping cardboard on your bumper ends when installing or removing will save your paint. this could be a great thread
