I've got a car that's got cancer, bad.
When pulling parts like frame rails and rocker panels and replacing them, what's the prep to insure no more cancer?
Weld through primer, weld em in, good to go, or is there a way and a product to put inside to make they stay rust free? Add drain holes?
In the world of structural welding, there is no such thing called "weld through primer". A good primer over properly prepared metal ground away from the weld zone is the proper repair from my point of view.
There is an awesome product called "Like 90" that penetrates the weld zone better than any other product I have found.
