if this is just from salt, nothing to add. if there is another place where water is entering(cowl, firewall hole), i would patch that first.
had an 81 chevy 1/2 ton. cowl was rusting, allowed water to enter cab. rusted floor, moved to rocker then out cab at the rear. would have been so much work involved, i was this was in 1987. i didn't have tools, experience, place to work. long story longer, i tried to patch the rust by placing melted tar, liquid rubber, ceramic pump coating but nothing worked because i kept the rust in place.
why did i tell this story? don't know. felt good to let it out after 28 years.
