Tackling the bottom of the spare tire well. Several spots of rust... Circled with a marker.
So... had to fabricate sheetmetal with a groove pressed in for rigidity. I've got a lot to go in terms of shaping and cutting to size but wanted to post the first day of effort here.
Had a blast dreaming this process up. I used my arbor press, routered out piece of plywood and a piece of hardwood as the press. Came out pretty well.
