I have a replacement door I got from Vern and I am now refurbing it. There are a few rust holes in the bottom about a dime size that I would like your expert opinion on the repair. The M door has a large formed portion in the center inside that is in the way of decent access to the inside bottom of the door.
What is the best way to fix these holes?
Since I can't really get to the inside bottom of the door, how does on treat and coat to prevent further rust and to seal?
