I have seen these companies that use spray welding to fill holes in metal and it looks great, not cheap to get into but looks like it works.
My concern is that they are fixing rusted metal. I have yet to meet anyone who will gaurantee rust repairs (except for panel replacement). When a object is fixed that has no access to the back side (like a windshield post) what is stoping the rust from creaping farther?
