I am restoring a 70' AMC Javelin that has a couple of small rust holes about 1/16" in one lower rear quarter panel. The trunk drop down to quarter panel opening is only about a 1/2" or less and tapers down to the pinch weld, I can barely see in there with a light and mirror. What I would like to do is chemically clean or etch the panel inside then seal/fill it with epoxy, POR-15 product or other suitable filler to prevent anymore rust, is it possible to do a permanent repair without major surgery? Any suggestions?
