Just lookin for some sound advice about the prep work on my 76 c10 truck cab,i took thr liberty of cutting the rocker's pannel's and cab corner's out of my truck cab to save a few green back's.It's been some time since i've had a chance to install the new pannel's,so thing's got a bit rusty on me.I shot some primer over the metal after i cut the old one's out,but it's getting pretty rusty. I not the best body man out there by a long shot,so i need all the help i can get.Was wondering if i should use (Klean-Strip)product to rid the rust,or just sand blast.I've got a friend that will weld the pannals on for around $250.00.But i just know that he's not gonna tackle the rust the way i want it done,(please advise)
