The wof guy failed me on a rust spot in the front right chassis rail and said to see a panel beater before booking a re check. I'm a decent welder but not certified. I've cut the rust out and cleaned it up. Wondering whether to weld it and take it in for recheck or take it to a panel beater. It is in the box section of the chassis and is localised, but there will be no way to prove it's been done properly and theres no other internal rust once it's been fixed. Any thoughts?
