what is the obsession some people have with self etching primer?
I do not know the history of self etching primer but I would think it was originally developed to treat new metal to accept paint without sanding.. as in stamp a part, dip it in self etching primer, rinse, prime, top coat, assembly line style.
From there it trickled down to the repair shops back before the day.
Now it is an ancient dinosaur that won't die.
How close to reallity is my thought?
