Looking for some advice. I was prepping to weld in a patch panel and noticed where I sanded through on a edge there was what looked like a reddish brown layer under the epoxy primer. There is also an area that appears to be showing rust coming through on the door pillar. I had my cab sand blasted and epoxy primed a couple of years ago and the person that did it had it back to me in a week. I don't know how long between blasting and priming. I realize it will need re-priming but am I going to have to strip the cab again? Thoughts?
Thank you!
