The kit from Harbor Freight came with a slide hammer and studs and welding tips. Here's the link http://www.harborfreight.com/stud-we...kit-98357.html
It seems to work okay for me and do the job it's supposed to do, although I may be wrong since I've never used one before. Some people have had problems with the slide hammer locking on the studs, but so far I haven't experienced that. After I do a bit more work on things I'll post some before/after pics. I'll say one thing, it's more labor intensive than I thought it would be. No wonder body shops charge so much for labor.
My neighbor came over to watch me and he said the panel looked like the guy in the movies with the spikes sticking out of his head, The Punisher maybe? Gave me a good laugh.
