Step 1: Scrape and Sand
The first step was to scrape off the loose paint surrounding the rust spot, and to sand off most of the rust. I found, under the outer layer of metal, what I thought were additional layers of rusted, chipping metal, was actually dense foam padding. I scraped the rest of the metal chips off of the foam.
Step 2: Building Up (part 1)
At this point, I used a metal mesh body patch (bondo brand) to fill the hole, replace the missing metal, and give the bondo a place to adhere to. Using regular scissors, I cut the mesh to approximately the right shape, and then began fitting it into the hole between the metal and the foam.
Step 3: Building Up (part 2)
The next step was patching the hole with bondo body filler. This was interesting, as I'd never used the stuff before. It comes with two parts, the body filler putty (grey), and the hardener cream (red), which you mix together, and then apply. The instructions say to use a golf-ball sized amount of putty and an inch and a half of hardener.
Step 4: Primer
The next step was to apply a primer over the patch. I used a self etching, sandable primer, and followed the instructions on the can. I taped over the edges while I was working. Once I was done, I used a 600 grit sandpaper to soften the edge of the primer, and roughen the surrounding paint. That's me sanding.
Step 5
The final step was painting. The first color I used wasn't right.
