Robert,
Thanks for the information. I definitely will NOT be using an etch primer. I am also staying away from soda blasting as I have quite a bit of surface rust as well as old coatings to remove and have heard soda blasting will not remove rust. I have been considering "Dustless Blasting" of my sheet metal components to avoid the possibility of panel warpage from sand/media blasting, followed up with epoxy primer. Your thoughts?
Thanks again!
