Started on my fenders, which actually was a happy surprise. After taking the paint down, I found the the major rust was only about 5", the rest of the surrounding metal was clean and rust free. I trimmed the bad stuff out leaving a nice square hole in the fender.
Got my patch made and started the welding process....yikes I'm rusty. I haven't welded sheetmetal in probably 3 years, wire setting are a *****.
I did manage to get a nice clean patch after all was said and done, time for the filler!
