this car frame need some sections re-constructed due to rust, and enough
other work that everything comes off the frame is an actual frame, has
plastic body

has anyone ever galvanized a car frame - what prep is needed beside basic
oil/dirt/paint removal

it could be electrolytically de-rusted (tank made from large poly sheet
and wood frame on concrete floor), or will the galvanizing process handle
leftover surface rust?

only a few of these car frames made, buying another means basically
buying another car
