I have a 67 suburban that was stripped and prime 18 yrs. ago, is now covered with surface rust. Has rust out needing repair panels. What is the best order/steps and products to bring her back to life? Am thinking rust remover, self etching weld thru primer, patch panels, eoxy primer, body filler, primer and finally paint. But have never done anything like this, REALLY DO NOT KNOW. Please help.
