I bought one of these about 25 years ago. http://dentfix888.com/?product=stud-welder I had a lot more time to work on jalopies back then. Or Maybe it was because I was 25 years younger and put in a lot more hours a day. I really like it. They are making one for aluminum now because of the aluminum that Ford uses. I am toying the idea of buying the aluminum model because our trucks are all rived aluminum. We outsource large paint jobs, but painting small repairs works good enough with a Sata HLVP gun. Almost anyone can match paint with them. All but 2 of our trucks are refrigerator white and that simplifies things.
