So what do you guys recommend for undercoating? My factory undercoating is practically falling off in some places due to the damage posted above, and I want to get something stronger on there. I've heard good things and bad things about POR-15, I know there's more out there but I haven't done much research on it yet. Any input would be appreciated.
