The body shop pulled, pounded and primered for the $840. And they ground down a weld bead line that was already there. The other insurance paid.
They used a 2-part epoxy primer and said it was impervious to the elements. They didn't do the full top coat because what I had there was Rustoleum (so much better than Krylon, I think).
Here's a pic. The "before" picture link is in my first post. Thanks guys.
