 ones that don't do it the only ones that really don't do it are the ones that the vehicles are so rusted or a frame has a rust hole through it that we have to tell them i'm sorry we can't put this safety hazard it's yeah it's not safe anymore um and my tahoe even is getting a body mount that is so rusted that i gotta watch it and i'm gonna have to get scrapped that thing into probably another year or less because i've let it go so that'll protect it as far as the paint go
