Well, I think I finally got these holes fixed yesterday...and ended up paying nothing to have it done!
I dropped my TJ off at the shop yesterday morning to have the holes welded up. When I went to pick up my Jeep yesterday afternoon, they gentlemen there said "I welded a patch in for the large hole, but on the smaller holes I used a special epoxy". He also stated that he was concerned about the two back holes being over the fuel tank. I told him that I appreciated his concern, but I would have preferred that he call me and let me know prior to using repair methods that were not discussed. I also asked to see what epoxy he had used and he went and got an application gun that had this stuff called Valvoline Pliogrip in it. From what I can tell it is pretty good stuff and he swore up and down that I would never have any problems with it. The guy there told me he could tell I was quite concerned about the repair, so the work would be at no charge. I'm not one to take handouts, so I insisted that I at least pay him $25-50 for the patch that was welded in....he said don't worry about it. I thanked him for his generosity and told him that I would remember that next time I needed some work done.
Just thought I'd let you guys know what happened.
