Rusty Floor Pans

Today I finished patching up the floor boards and sealed it all up. Below is a brief overview of the process. Pictures to follow.

1. I planned.
2. I revised my plan a lot after measuring and checking cost.
3. I remeasured and cut my patch material with a foot shear.
4. I used an air diegrinder with a cutoff wheel to cut a whole 1 inch on all sides smaller than my patch.
5. I used a wire wheel on a drill to remove all of the rust remaining on the floor and rough up the paint for a new coat.
6. With the surface clean I sprayed the exposed surface with rust oleum to stop any rust from reappearing
7. Then I applied a thick line of sealant around the 1" perimeter of the holes. I wanted to use a tar to seal it but I could only find a silicone sealant at the hardware store so I went with that.
8. Starting with one corner I drilled an 1/8" hole and riveted the plate down. I used steel rivets with backing washers.
9. Then I continued around the patch at 2" intervals drilling and then riveting to make sure everything lines up and the holes don't end up moving around as the patch is riveted down.
10. With the patches secure I sprayed the rest of the floor pan area with a heavy coat of rust oleum. I chose a semi-gloss black for the interior because the red looks terrible.
