The spot weld that holds the rubber hose type piece in place on one of my front outer bumper brackets is sharp and jagged. It is an ugly weld and looks like someone's first attempt at learning to MIG weld. Is this someone repair or an ugly factory weld? I have scratched myself working around it and would like to grind it down. July built SJ Mach One. Also, what is the purpose of the rubber hose pieces?
